Pull btrfs updates from David Sterba:
"Highlights:
- chunks that have been trimmed and unchanged since last mount are
tracked and skipped on repeated trims
- use hw assissed crc32c on more arches, speedups if native
instructions or optimized implementation is available
- the RAID56 incompat bit is automatically removed when the last
block group of that type is removed
Fixes:
- fsync fix for reflink on NODATACOW files that could lead to ENOSPC
- fix data loss after inode eviction, renaming it, and fsync it
- fix fsync not persisting dentry deletions due to inode evictions
- update ctime/mtime/iversion after hole punching
- fix compression type validation (reported by KASAN)
- send won't be allowed to start when relocation is in progress, this
can cause spurious errors or produce incorrect send stream
Core:
- new tracepoints for space update
- tree-checker: better check for end of extents for some tree items
- preparatory work for more checksum algorithms
- run delayed iput at unlink time and don't push the work to cleaner
thread where it's not properly throttled
- wrap block mapping to structures and helpers, base for further
refactoring
- split large files, part 1:
- space info handling
- block group reservations
- delayed refs
- delayed allocation
- other cleanups and refactoring"

Merge branch 'proc-cmdline' (/proc/<pid>/cmdline fixes)
This fixes two problems reported with the cmdline simplification and
cleanup last year:
- the setproctitle() special cases didn't quite match the original
semantics, and it can be noticeable:
https://lore.kernel.org/lkml/alpine.LNX.2.21.1904052326230.3249@kich.toxcorp.com/
- it could leak an uninitialized byte from the temporary buffer under
the right (wrong) circustances:
https://lore.kernel.org/lkml/20190712160913.17727-1-izbyshev@ispras.ru/
It rewrites the logic entirely, splitting it into two separate commits
(and two separate functions) for the two different cases ("unedited
cmdline" vs "setproctitle() has been used to change the command line").
* proc-cmdline:
/proc/<pid>/cmdline: add back the setproctitle() special case
/proc/<pid>/cmdline: remove all the special cases

/proc/<pid>/cmdline: add back the setproctitle() special case
This makes the setproctitle() special case very explicit indeed, and
handles it with a separate helper function entirely. In the process, it
re-instates the original semantics of simply stopping at the first NUL
character when the original last NUL character is no longer there.
[ The original semantics can still be seen in mm/util.c: get_cmdline()
that is limited to a fixed-size buffer ]
This makes the logic about when we use the string lengths etc much more
obvious, and makes it easier to see what we do and what the two very
different cases are.
Note that even when we allow walking past the end of the argument array
(because the setproctitle() might have overwritten and overflowed the
original argv[] strings), we only allow it when it overflows into the
environment region if it is immediately adjacent.
[ Fixed for missing 'count' checks noted by Alexey Izbyshev ]

/proc/<pid>/cmdline: remove all the special cases
Start off with a clean slate that only reads exactly from arg_start to
arg_end, without any oddities. This simplifies the code and in the
process removes the case that caused us to potentially leak an
uninitialized byte from the temporary kernel buffer.
Note that in order to start from scratch with an understandable base,
this simplifies things _too_ much, and removes all the legacy logic to
handle setproctitle() having changed the argument strings.
We'll add back those special cases very differently in the next commit.

HMM patches for 5.3
Improvements and bug fixes for the hmm interface in the kernel:
- Improve clarity, locking and APIs related to the 'hmm mirror' feature
merged last cycle. In linux-next we now see AMDGPU and nouveau to be
using this API.
- Remove old or transitional hmm APIs. These are hold overs from the past
with no users, or APIs that existed only to manage cross tree conflicts.
There are still a few more of these cleanups that didn't make the merge
window cut off.
- Improve some core mm APIs:
* export alloc_pages_vma() for driver use
* refactor into devm_request_free_mem_region() to manage
DEVICE_PRIVATE resource reservations
* refactor duplicative driver code into the core dev_pagemap
struct
- Remove hmm wrappers of improved core mm APIs, instead have drivers use
the simplified API directly
- Remove DEVICE_PUBLIC
- Simplify the kconfig flow for the hmm users and core code

Merge tag 'for-5.3/io_uring-20190711' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe:
"This contains:
- Support for recvmsg/sendmsg as first class opcodes.
I don't envision going much further down this path, as there are
plans in progress to support potentially any system call in an
async fashion through io_uring. But I think it does make sense to
have certain core ops available directly, especially those that can
support a "try this non-blocking" flag/mode. (me)
- Handle generic short reads automatically.
This can happen fairly easily if parts of the buffered read is
cached. Since the application needs to issue another request for
the remainder, just do this internally and save kernel/user
roundtrip while providing a nicer more robust API. (me)
- Support for linked SQEs.
This allows SQEs to depend on each other, enabling an application
to eg queue a read-from-this-file,write-to-that-file pair. (me)
- Fix race in stopping SQ thread (Jackie)"

f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancement: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fix: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl0mlKIACgkQQBSofoJI UNI2Ow//e4QxinKVdgA6F2wx0CkdSreqfzQbA1t+6pcWgzCgLfj4dpOuSp8Yu1NT aG6YFfUxjtUNN8D85WqJ+6qKt0gFBoxjQXDvvbxLFB9Xoa2XqzFrHW8xenSRHppj V63Yye5Z+Qgss65hTktgHMWSi4mUWRq76t1lFBprXm41uC036rIQCSYioztcLQCN fFi2xfkFHf7vIIg6ZrCy22wNSCWL9X6dzKftIZ6LSz+jkPGEard1D/OUYLMMQ4YG b5DS0LEWbudn1vwALPPXwTHgZuG12W581MsHUsu2FIyenGGTk7EIZfNBN6cGfIMk NsEMnanFvXp7ZYP6HQnZlSkoBRIkD2JpYh7bFxTklw4H09GJxYFksed8uqNoDRog GPcNZjKSm0wCUHe2awOhF9kRXMFnwIR7m4DNOQHH1MYmpp3ponGsbfYy3J/qLS5y Smh8pcbsttDMQ0NaWZznby2bSEv9k9R9CoqE5sKCNDnh6Ky8WjK8x6xt3wrPG6h8 jI7venvHvJbFpxAmnKDzflZrlGj95pg0j0DAk07ql/9i8YPfRrlBKv8jOo+7aRWC jIO70URGDO6R/o5XdRqx6u8DOE1JPVP+6XzsT6MdDtBlxE+TbcTPRt3RzEgmo1d3 CI0jq0IRDTDZJITmQoQKCS85OZDyaAe2iHUPwSjCEuDex5lynuY= =S2ZS -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads.

- Claim maintainership of various loose xfs documentation and header
files.
- Use struct bio directly for log buffer IOs instead of struct xfs_buf.

- Add a multithreaded iwalk implementation to speed up quotacheck on
fast storage with many CPUs.
- Remove unnecessary return values in logging teardown functions.

bulk_ireq structure at the head instead of the pointerhappy mess we
had before.
- Enable userspace to constrain bulkstat returns to a single AG or a

Pull xfs updates from Darrick Wong:
"In this release there are a significant amounts of consolidations and
cleanups in the log code; restructuring of the log to issue struct
bios directly; new bulkstat ioctls to return v5 fs inode information

multithreaded inode walks (e.g. quotacheck); and a reduction in memory
usage in the online scrub code leading to reduced runtimes.

Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

mm, oom: remove redundant task_in_mem_cgroup() check
oom_unkillable_task() can be called from three different contexts i.e. global OOM, memcg OOM and oom_score procfs interface. At the moment oom_unkillable_task() does a task_in_mem_cgroup() check on the given process. Since there is no reason to perform task_in_mem_cgroup() check for global OOM and oom_score procfs interface, those contexts provide NULL memcg and skips the task_in_mem_cgroup() check. However for memcg OOM context, the oom_unkillable_task() is always called from mem_cgroup_scan_tasks() and thus task_in_mem_cgroup() check becomes redundant and effectively dead code. So, just remove the task_in_mem_cgroup() check altogether.

mm: vmalloc: show number of vmalloc pages in /proc/meminfo
Vmalloc() is getting more and more used these days (kernel stacks, bpf and
percpu allocator are new top users), and the total % of memory consumed by
vmalloc() can be pretty significant and changes dynamically.
/proc/meminfo is the best place to display this information: its top goal
is to show top consumers of the memory.
Since the VmallocUsed field in /proc/meminfo is not in use for quite a
long time (it has been defined to 0 by

mm: smaps: split PSS into components
Report separate components (anon, file, and shmem) for PSS in smaps_rollup. This helps understand and tune the memory manager behavior in consumer devices, particularly mobile devices. Many of them (e.g. chromebooks and Android-based devices) use zram for anon memory, and perform disk reads for discarded file pages. The difference in latency is large (e.g. reading a single page from SSD is 30 times slower than decompressing a zram page on one popular device), thus it is useful to know how much of the PSS is anon vs. file. All the information is already present in /proc/pid/smaps, but much more expensive to obtain because of the large size of that procfs entry. This patch also removes a small code duplication in smaps_account, which would have gotten worse otherwise. Also updated Documentation/filesystems/proc.txt (the smaps section was a bit stale, and I added a smaps_rollup section) and Documentation/ABI/testing/procfs-smaps_rollup.

ocfs2: use kmemdup rather than duplicating its implementation
kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

ocfs: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Also, because there is no need to save the file dentry, remove all of the variables that were being saved, and just recursively delete the whole directory when shutting down, saving a lot of logic and local variables.

ocfs2 file system uses locking_state file under debugfs to dump each ocfs2 file system's dlm lock resources, but the users ever encountered some hang(deadlock) problems in ocfs2 file system. I'd like to add first lock wait time in locking_state file, which can help the upper scripts detect these deadlock problems via comparing the first lock wait time with the current time.

ocfs2: add locking filter debugfs file
Add locking filter debugfs file, which is used to filter lock resources dump from locking_state debugfs file. We use d_filter_secs field to filter lock resources dump, the default d_filter_secs(0) value filters nothing, otherwise, only dump the last N seconds active lock resources. This enhancement can avoid dumping lots of old records. The d_filter_secs value can be changed via locking_filter file.

ocfs2: add last unlock times in locking_state
ocfs2 file system uses locking_state file under debugfs to dump each ocfs2 file system's dlm lock resources, but the dlm lock resources in memory are becoming more and more after the files were touched by the user. it will become a bit difficult to analyze these dlm lock resource records in locking_state file by the upper scripts, though some files are not active for now, which were accessed long time ago. Then, I'd like to add last pr/ex unlock times in locking_state file for each dlm lock resource record, the the upper scripts can use last unlock time to filter inactive dlm lock resource record.

ocfs2/dlm: use struct_size() helper
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct dlm_migratable_lockres
{
...
struct dlm_migratable_lock ml[0]; // 16 bytes each, begins at byte 112
};
Make use of the struct_size() helper instead of an open-coded version in
order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct dlm_migratable_lockres) + (mres->num_locks * sizeof(struct dlm_migratable_lock))
with:
struct_size(mres, ml, mres->num_locks)
Notice that, in this case, variable sz is not necessary, hence it is
removed.
This code was detected with the help of Coccinelle.

Highlights:
- Add a new /proc/fs/nfsd/clients/ directory which exposes some long-requested information about NFSv4 clients (like open files) and allows forced revocation of client state. - Replace the global duplicate reply cache by a cache per network namespace; previously, a request in one network namespace could incorrectly match an entry from another, though we haven't seen this in production. This is the last remaining container bug that I'm aware of; at this point you should be able to run separate nfsd's in each network namespace, each with their own set of exports, and everything should work. - Cleanup and modify lock code to show the pid of lockd as the owner of NLM locks. This is the correct version of the bugfix originally attempted in |
