Although it isn't used directly by the ioctls,
"struct fsverity_descriptor" is required by userspace programs that need
to compute fs-verity file digests in a standalone way. Therefore
it's also needed to sign files in a standalone way.Similarly, "struct fsverity_formatted_digest" (previously called
"struct fsverity_signed_digest" which was misleading) is also needed to
sign files if the built-in signature verification is being used.Therefore, move these structs to the UAPI header.
While doing this, try to make it clear that the signature-related fields
in fsverity_descriptor aren't used in the file digest computation.Acked-by: Luca Boccassi

I originally chose the name "file measurement" to refer to the fs-verity
file digest to avoid confusion with traditional full-file digests or
with the bare root hash of the Merkle tree.But the name "file measurement" hasn't caught on, and usually people are
calling it something else, usually the "file digest". E.g. see
"struct fsverity_digest" and "struct fsverity_formatted_digest", the
libfsverity_compute_digest() and libfsverity_sign_digest() functions in
libfsverity, and the "fsverity digest" command.Having multiple names for the same thing is always confusing.
So to hopefully avoid confusion in the future, rename
"fs-verity file measurement" to "fs-verity file digest".This leaves FS_IOC_MEASURE_VERITY as the only reference to "measure" in
the kernel, which makes some amount of sense since the ioctl is actively
"measuring" the file.I'll be renaming this in fsverity-utils too (though similarly the
'fsverity measure' command, which is a wrapper for
FS_IOC_MEASURE_VERITY, will stay).Acked-by: Luca Boccassi

The name "struct fsverity_signed_digest" is causing confusion because it
isn't actually a signed digest, but rather it's the way that the digest
is formatted in order to be signed. Rename it to
"struct fsverity_formatted_digest" to prevent this confusion.Also update the struct's comment to clarify that it's specific to the
built-in signature verification support and isn't a requirement for all
fs-verity users.I'll be renaming this struct in fsverity-utils too.

We will add a new "compress_mode" mount option to control file
compression mode. This supports "fs" and "user". In "fs" mode (default),
f2fs does automatic compression on the compression enabled files.
In "user" mode, f2fs disables the automaic compression and gives the
user discretion of choosing the target file and the timing. It means
the user can do manual compression/decompression on the compression
enabled files using ioctls.Signed-off-by: Daeho Jeong

The direct-io.c file used to have just two exported symbols:
- dio_end_io()
- __blockdev_direct_IO()The first one was removed by changeset
c33fe275b530 ("fs: remove no longer used dio_end_io()")And the last one is used on most places indirectly, via
the inline macro blockdev_direct_IO() provided by fs.h.
Yet, neither the macro or the function have kernel-doc
markups.So, drop the inclusion of fs/direct-io.c at the docs.

"The siginificant new ext4 feature this time around is Harshad's new
fast_commit mode.In addition, thanks to Mauricio for fixing a race where mmap'ed pages
that are being changed in parallel with a data=journal transaction
commit could result in bad checksums in the failure that could cause
journal replays to fail.Also notable is Ritesh's buffered write optimization which can result
in significant improvements on parallel write workloads. (The kernel
test robot reported a 330.6% improvement on fio.write_iops on a 96
core system using DAX)Besides that, we have the usual miscellaneous cleanups and bug fixes"

addition, we could improve the decompression speed significantly by

bugs in compression support, I feel that it becomes more stable so
that I could give it a try in production.Enhancements:
- suport zone capacity in NVMe Zoned Namespace devices
- introduce in-memory current segment management
- add standart casefolding support
- support age threshold based garbage collection
- improve decompression speed by changing virtual mapping methodBug fixes:
- fix condition checks in some ioctl() such as compression, move_range, etc
- fix 32/64bits support in data structures
- fix memory allocation in zstd decompress
- add some boundary checks to avoid kernel panic on corrupted image

The :c:type: tag has problems with Sphinx 3.x, as structs
there should be declared with c:struct.So, remove them, relying at automarkup.py extension to
convert them into cross-references.Signed-off-by: Mauro Carvalho Chehab

The :c:type:`foo` only works properly with structs before
Sphinx 3.x.On Sphinx 3.x, structs should now be declared using the
.. c:struct, and referenced via :c:struct tag.As we now have the automarkup.py macro, that automatically
convert:
struct foointo cross-references, let's get rid of that, solving
several warnings when building docs with Sphinx 3.x.Reviewed-by: André Almeida # blk-mq.rst

Pull driver core updates from Greg KH:
"Here is the "big" set of driver core patches for 5.10-rc1They include a lot of different things, all related to the driver core
and/or some driver logic:- sysfs common write functions to make it easier to audit sysfs
attributes- device connection cleanups and fixes
- devm helpers for a few functions
- NOIO allocations for when devices are being removed
- minor cleanups and fixes
All have been in linux-next for a while with no reported issues"
