Merge tag 'netfs-prep-20220318' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull netfs updates from David Howells:
"Netfs prep for write helpers.
Having had a go at implementing write helpers and content encryption
support in netfslib, it seems that the netfs_read_{,sub}request
structs and the equivalent write request structs were almost the same
and so should be merged, thereby requiring only one set of
alloc/get/put functions and a common set of tracepoints.
Merging the structs also has the advantage that if a bounce buffer is
added to the request struct, a read operation can be performed to fill
the bounce buffer, the contents of the buffer can be modified and then
a write operation can be performed on it to send the data wherever it
needs to go using the same request structure all the way through. The
I/O handlers would then transparently perform any required crypto.
This should make it easier to perform RMW cycles if needed.
The potentially common functions and structs, however, by their names
all proclaim themselves to be associated with the read side of things.
The bulk of these changes alter this in the following ways:
- Rename struct netfs_read_{,sub}request to netfs_io_{,sub}request.
- Rename some enums, members and flags to make them more appropriate.
- Adjust some comments to match.
- Drop "read"/"rreq" from the names of common functions. For
instance, netfs_get_read_request() becomes netfs_get_request().
- The ->init_rreq() and ->issue_op() methods become ->init_request()
and ->issue_read(). I've kept the latter as a read-specific
function and in another branch added an ->issue_write() method.
The driver source is then reorganised into a number of files:
fs/netfs/buffered_read.c Create read reqs to the pagecache
fs/netfs/io.c Dispatchers for read and write reqs
fs/netfs/main.c Some general miscellaneous bits
fs/netfs/objects.c Alloc, get and put functions
fs/netfs/stats.c Optional procfs statistics.
and future development can be fitted into this scheme, e.g.:
fs/netfs/buffered_write.c Modify the pagecache
fs/netfs/buffered_flush.c Writeback from the pagecache
fs/netfs/direct_read.c DIO read support
fs/netfs/direct_write.c DIO write support
fs/netfs/unbuffered_write.c Write modifications directly back
Beyond the above changes, there are also some changes that affect how
things work:
- Make fscache_end_operation() generally available.
- In the netfs tracing header, generate enums from the symbol ->
string mapping tables rather than manually coding them.
- Add a struct for filesystems that uses netfslib to put into their
inode wrapper structs to hold extra state that netfslib is
interested in, such as the fscache cookie. This allows netfslib
functions to be set in filesystem operation tables and jumped to
directly without having to have a filesystem wrapper.
- Add a member to the struct added above to track the remote inode
length as that may differ if local modifications are buffered. We
may need to supply an appropriate EOF pointer when storing data (in
AFS for example).
- Pass extra information to netfs_alloc_request() so that the
->init_request() hook can access it and retain information to
indicate the origin of the operation.
- Make the ->init_request() hook return an error, thereby allowing a
filesystem that isn't allowed to cache an inode (ceph or cifs, for
example) to skip readahead.
- Switch to using refcount_t for subrequests and add tracepoints to
log refcount changes for the request and subrequest structs.
- Add a function to consolidate dispatching a read request. Similar
code is used in three places and another couple are likely to be
added in the future"

Merge tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator fixes from Jason Donenfeld:
- If a hardware random number generator passes a sufficiently large
chunk of entropy to random.c during early boot, we now skip the
"fast_init" business and let it initialize the RNG.
This makes CONFIG_RANDOM_TRUST_BOOTLOADER=y actually useful.
- We already have the command line `random.trust_cpu=0/1` option for
RDRAND, which let distros enable CONFIG_RANDOM_TRUST_CPU=y while
placating concerns of more paranoid users.
Now we add `random.trust_bootloader=0/1` so that distros can
similarly enable CONFIG_RANDOM_TRUST_BOOTLOADER=y.
- Re-add a comment that got removed by accident in the recent revert.
- Add the spec-compliant ACPI CID for vmgenid, which Microsoft added to
the vmgenid spec at Ard's request during earlier review.
- Restore build-time randomness via the latent entropy plugin, which
was lost when we transitioned to using a hash function.

We want people to mark their patches with net and net-next in the subject.
Many miss doing that. Move the FAQ section which points that out up, and
place it after the section which enumerates the trees, that seems like
a pretty logical place for it. Since the two sections are together we
can remove a little bit (not too much) of the repetition.
v2: also remove the text for non-git setups, we want people to use git.

The LLVM make variable allows a developer to quickly switch between the
GNU and LLVM tools. However, it does not handle versioned binaries, such
as the ones shipped by Debian, as LLVM=1 just defines the tool variables
with the unversioned binaries.
There was some discussion during the review of the patch that introduces
LLVM=1 around versioned binaries, ultimately coming to the conclusion
that developers can just add the folder that contains the unversioned
binaries to their PATH, as Debian's versioned suffixed binaries are
really just symlinks to the unversioned binaries in /usr/lib/llvm-#/bin:
$ realpath /usr/bin/clang-14
/usr/lib/llvm-14/bin/clang
$ PATH=/usr/lib/llvm-14/bin:$PATH make ... LLVM=1
However, that can be cumbersome to developers who are constantly testing
series with different toolchains and versions. It is simple enough to
support these versioned binaries directly in the Kbuild system by
allowing the developer to specify the version suffix with LLVM=, which
is shorter than the above suggestion:
$ make ... LLVM=-14
It does not change the meaning of LLVM=1 (which will continue to use
unversioned binaries) and it does not add too much additional complexity
to the existing $(LLVM) code, while allowing developers to quickly test
their series with different versions of the whole LLVM suite of tools.
Some developers may build LLVM from source but not add the binaries to
their PATH, as they may not want to use that toolchain systemwide.
Support those developers by allowing them to supply the directory that
the LLVM tools are available in, as it is no more complex to support
than the version suffix change above.
$ make ... LLVM=/path/to/llvm/
Update and reorder the documentation to reflect these new additions.
At the same time, notate that LLVM=0 is not the same as just omitting it
altogether, which has confused people in the past.

In the remoteproc core, it's now possible to mark the sysfs attributes

clk_set_rate_range() works so that the frequency is re-evaulated each time the
rate is changed. Previously we wouldn't let clk providers see a rate that was
different if it was still within the range, which could be bad for power if the
clk could run slower when a range expands. Now the clk provider can decide to
do something differently when the constraints change. This broke Nvidia's clk
driver so we had to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk framework
that we're going to extend in the next release. It already made it easy to find
corner cases in the rate range patches so I'm excited to see it cover more clk
code and increase our confidence in core framework patches in the future. I
also added a kunit test for the basic clk gate code and that work will continue
to cover more basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and additions.
Qualcomm again dominates the diffstat here with lots more SoCs being supported
and i.MX follows afer that with a similar number of SoCs gaining clk drivers.
Beyond those large additions there's drivers being modernized to use
clk_parent_data so we can move away from global string names for all the clks
in an SoC. Finally there's lots of little fixes all over the clk drivers for
typos, warnings, and missing clks that aren't critical and get batched up

mostly work with it omitted, but for correctness the path should be

'dma-ranges' in the example is written for cell sizes of 2 cells, but
the schema and example specify sizes of 1 cell. As the h/w has a bus
address of >32-bits, cell sizes of 2 is correct. Update the schema's
'#address-cells' and '#size-cells' to be 2 and adjust the example
throughout.
There's no error currently because dtc only checks 'dma-ranges' is a
correct multiple number of cells (3) and the schema checking is based on
bracketing of entries.

To avoid failure of dt_binding_check perform a slight refactoring
of the examples: the main block is kept, but that required fixing
the address and size cells, plus the inclusion of missing dt-bindings
headers, required to parse some of the values assigned to various
properties.

- export symbol cleanups and other core cleanups from Jiri Slaby
- new sunplus and mvebu uart drivers (amazing that people are
still creating new uarts...)
- samsung serial driver cleanups
- ldisc 29 is now "reserved" for experimental/development line
disciplines
- lots of other tiny fixes and cleanups to serial drivers and
