fs: Add FOP_HUGE_PAGES
Instead of checking for specific file_operations, add a bit to
file_operations which denotes a file that only contain hugetlb pages.
This lets us make hugetlbfs_file_operations static, and removes
is_file_shm_hugepages() completely.

orangefs: cleanup uses of strncpy
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

There is some care taken to ensure these destination buffers are
NUL-terminated by bounding the strncpy()'s by ORANGEFS_NAME_MAX - 1 or
ORANGEFS_MAX_SERVER_ADDR_LEN - 1. Instead, we can use the new 2-argument
version of strscpy() to guarantee NUL-termination on the destination
buffers while simplifying the code.

Based on usage with printf-likes, we can see these buffers are expected
to be NUL-terminated:
|	gossip_debug(GOSSIP_NAME_DEBUG,
|			"%s: doing lookup on %s under %pU,%d\n",
|			__func__,
|			new_op->upcall.req.lookup.d_name,
|			&new_op->upcall.req.lookup.parent_refn.khandle,
|			new_op->upcall.req.lookup.parent_refn.fs_id);
...
|	gossip_debug(GOSSIP_SUPER_DEBUG,
|			"Attempting ORANGEFS Remount via host %s\n",
|			new_op->upcall.req.fs_mount.orangefs_config_server);

NUL-padding isn't required for any of these destination buffers as
they've all been zero-allocated with op_alloc() or kzalloc().

nilfs2: fix out-of-range warning
clang-14 points out that v_size is always smaller than a 64KB
page size if that is configured by the CPU architecture:

fs/nilfs2/ioctl.c:63:19: error: result of comparison of constant 65536 with expression of type '__u16' (aka 'unsigned short') is always false [-Werror,-Wtautological-constant-out-of-range-compare]

fs: claw back a few FMODE_* bits
There's a bunch of flags that are purely based on what the file
operations support while also never being conditionally set or unset.
IOW, they're not subject to change for individual files. Imho, such
flags don't need to live in f_mode they might as well live in the fops
structs itself. And the fops struct already has that lonely
mmap_supported_flags member. We might as well turn that into a generic
fop_flags member and move a few flags from FMODE_* space into FOP_*
space. That gets us four FMODE_* bits back and the ability for new
static flags that are about file ops to not have to live in FMODE_*
space but in their own FOP_* space. It's not the most beautiful thing
ever but it gets the job done. Yes, there'll be an additional pointer
chase but hopefully that won't matter for these flags.

I suspect there's a few more we can move into there and that we can also
redirect a bunch of new flag suggestions that follow this pattern into
the fop_flags field instead of f_mode.

fs: Annotate struct file_handle with __counted_by() and use struct_size()
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

While there, use struct_size() helper, instead of the open-coded
version.

ecryptfs: Fix buffer size for tag 66 packet
The 'TAG 66 Packet Format' description is missing the cipher code and
checksum fields that are packed into the message packet. As a result,
the buffer allocated for the packet is 3 bytes too small and
write_tag_66_packet() will write up to 3 bytes past the end of the
buffer.

Fix this by increasing the size of the allocation so the whole packet
will always fit in the buffer.

This fixes the below kasan slab-out-of-bounds bug:

fs/writeback: avoid to writeback non-expired inode in kupdate writeback
In kupdate writeback, only expired inode (have been dirty for longer than
dirty_expire_interval) is supposed to be written back. However, kupdate
writeback will writeback non-expired inode left in b_io or b_more_io from
last wb_writeback. As a result, writeback will keep being triggered
unexpected when we keep dirtying pages even dirty memory is under
threshold and inode is not expired. To be more specific:
Assume dirty background threshold is > 1G and dirty_expire_centisecs is
> 60s. When we running fio -size=1G -invalidate=0 -ioengine=libaio
--time_based -runtime=60... (keep dirtying), the writeback will keep
being triggered as following:
wb_workfn
  wb_do_writeback
    wb_check_background_flush
      /*
       * Wb dirty background threshold starts at 0 if device was idle and
       * grows up when bandwidth of wb is updated. So a background
       * writeback is triggered.
       */
      wb_over_bg_thresh
      /*
       * Dirtied inode will be written back and added to b_more_io list
       * after slice used up (because we keep dirtying the inode).
       */
      wb_writeback

Writeback is triggered per dirty_writeback_centisecs as following:
wb_workfn
  wb_do_writeback
    wb_check_old_data_flush
      /*
       * Write back inode left in b_io and b_more_io from last wb_writeback
       * even the inode is non-expired and it will be added to b_more_io
       * again as slice will be used up (because we keep dirtying the
       * inode)
       */
      wb_writeback

Fix this by moving non-expired inode to dirty list instead of more io
list for kupdate writeback in requeue_inode.

Test as following:
/* make it more easier to observe the issue */
echo 300000 > /proc/sys/vm/dirty_expire_centisecs
echo 100 > /proc/sys/vm/dirty_writeback_centisecs
/* create a idle device */
mkfs.ext4 -F /dev/vdb
mount /dev/vdb /bdi1/
/* run buffer write with fio */
fio -name test -filename=/bdi1/file -size=800M -ioengine=libaio -bs=4K \
-iodepth=1 -rw=write -direct=0 --time_based -runtime=60 -invalidate=0

Fio result before fix (run three tests):
1360MB/s
1329MB/s
1455MB/s

Fio result after fix (run three tests):
1737MB/s
1729MB/s
1789MB/s

Writeback for non-expired inode is gone as expeted. Observe this with trace
writeback_start and writeback_written as following:
echo 1 > /sys/kernel/debug/tracing/events/writeback/writeback_start/enab
echo 1 > /sys/kernel/debug/tracing/events/writeback/writeback_written/enable

a4145ce1e7 bcachefs fixes for 6.9-rc1
Assorted bugfixes.
 
 Most are fixes for simple assertion pops; the most significant fix is
 for a deadlock in recovery when we have to rewrite large numbers of
 btree nodes to fix errors. This was incorrectly running out of the same
 workqueue as the core interior btree update path - we now give it its
 own single threaded workqueue.
 
 This was visible to users as "bch2_btree_update_start(): error:
 BCH_ERR_journal_reclaim_would_deadlock" - and then recovery hanging.

In case of hitting the file EOF, ceph_read_iter() needs to retrieve the
file size from MDS, and Fr caps aren't neccessary.

1065da21e5 ceph: stop copying to iter at EOF on sync reads
If EOF is encountered, ceph_sync_read() return value is adjusted down
according to i_size, but the "to" iter is advanced by the actual number
of bytes read.  Then, when retrying, the remainder of the range may be
skipped incorrectly.

Ensure that the "to" iter is advanced only until EOF.

96cf51accc exfat: do not sync parent dir if just update timestamp
When sync or dir_sync is enabled, there is no need to sync the
parent directory's inode if only for updating its timestamp.

1. If an unexpected power failure occurs, the timestamp of the
   parent directory is not updated to the storage, which has no
   impact on the user.

2. The number of writes will be greatly reduced, which can not
   only improve performance, but also prolong device life.

af02c72d0b exfat: convert exfat_find_empty_entry() to use dentry cache
Before this conversion, each dentry traversed needs to be read
from the storage device or page cache. There are at least 16
dentries in a sector. This will result in frequent page cache
searches.

After this conversion, if all directory entries in a sector are
used, the sector only needs to be read once.

ad584d73a2 Tracing updates for 6.9:
Main user visible change:
 
 - User events can now have "multi formats"
 
   The current user events have a single format. If another event is created
   with a different format, it will fail to be created. That is, once an
   event name is used, it cannot be used again with a different format. This
   can cause issues if a library is using an event and updates its format.
   An application using the older format will prevent an application using
   the new library from registering its event.
 
   A task could also DOS another application if it knows the event names, and
   it creates events with different formats.
 
   The multi-format event is in a different name space from the single
   format. Both the event name and its format are the unique identifier.
   This will allow two different applications to use the same user event name
   but with different payloads.
 
 - Added support to have ftrace_dump_on_oops dump out instances and
   not just the main top level tracing buffer.
 
 Other changes:
 
 - Add eventfs_root_inode
 
   Only the root inode has a dentry that is static (never goes away) and
   stores it upon creation. There's no reason that the thousands of other
   eventfs inodes should have a pointer that never gets set in its
   descriptor. Create a eventfs_root_inode desciptor that has a eventfs_inode
   descriptor and a dentry pointer, and only the root inode will use this.
 
 - Added WARN_ON()s in eventfs
 
   There's some conditionals remaining in eventfs that should never be hit,
   but instead of removing them, add WARN_ON() around them to make sure that
   they are never hit.
 
 - Have saved_cmdlines allocation also include the map_cmdline_to_pid array
 
   The saved_cmdlines structure allocates a large amount of data to hold its
   mappings. Within it, it has three arrays. Two are already apart of it:
   map_pid_to_cmdline[] and saved_cmdlines[]. More memory can be saved by
   also including the map_cmdline_to_pid[] array as well.
 
 - Restructure __string() and __assign_str() macros used in TRACE_EVENT().
 
   Dynamic strings in TRACE_EVENT() are declared with:
 
       __string(name, source)
 
   And assigned with:
 
      __assign_str(name, source)
 
   In the tracepoint callback of the event, the __string() is used to get the
   size needed to allocate on the ring buffer and __assign_str() is used to
   copy the string into the ring buffer. There's a helper structure that is
   created in the TRACE_EVENT() macro logic that will hold the string length
   and its position in the ring buffer which is created by __string().
 
   There are several trace events that have a function to create the string
   to save. This function is executed twice. Once for __string() and again
   for __assign_str(). There's no reason for this. The helper structure could
   also save the string it used in __string() and simply copy that into
   __assign_str() (it also already has its length).
 
   By using the structure to store the source string for the assignment, it
   means that the second argument to __assign_str() is no longer needed.
 
   It will be removed in the next merge window, but for now add a warning if
   the source string given to __string() is different than the source string
   given to __assign_str(), as the source to __assign_str() isn't even used
   and will be going away.
 
 - Added checks to make sure that the source of __string() is also the
   source of __assign_str() so that it can be safely removed in the next
   merge window.
 
   Included fixes that the above check found.
 
 - Other minor clean ups and fixes

a8922f7967 ceph: remove SLAB_MEM_SPREAD flag usage
The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was
removed as of v6.8-rc1, so it became a dead flag since the commit
16a1d96835 ("mm/slab: remove mm/slab.c and slab_def.h"). And the
series [1] went on to mark it obsolete to avoid confusion for users.
Here we can just remove all its users, which has no functional change.
