Merge tag 'xfs-5.20-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
"The biggest changes for this release are the log scalability
improvements, lockless lookups for the buffer cache, and making the
attr fork a permanent part of the incore inode in preparation for
directory parent pointers.

There's also a bunch of bug fixes that have accumulated since -rc5. I
might send you a second pull request with some more bug fixes that I'm
still working on.

Once the merge window ends, I will hand maintainership back to Dave
Chinner until the 6.1-rc1 release so that I can conduct the design
review for the online fsck feature, and try to get it merged.

Summary:

- Improve scalability of the XFS log by removing spinlocks and global
synchronization points.

- Add security labels to whiteout inodes to match the other
filesystems.

- Clean up per-ag pointer passing to simplify call sites.

- Reduce verifier overhead by precalculating more AG geometry.

- Implement fast-path lockless lookups in the buffer cache to reduce
spinlock hammering.

- Make attr forks a permanent part of the inode structure to fix a
UAF bug and because most files these days tend to have security
labels and soon will have parent pointers too.

- Clean up XFS_IFORK_Q usage and give it a better name.

- Fix more UAF bugs in the xattr code.

- SOB my tags.

- Fix some typos in the timestamp range documentation.

- Fix a few more memory leaks.

- Code cleanups and typo fixes.

- Fix an unlocked inode fork pointer access in getbmap"

Merge tag 'xfs-perag-conv-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs into xfs-5.20-mergeA

xfs: per-ag conversions for 5.20

This series drives the perag down into the AGI, AGF and AGFL access
routines and unifies the perag structure initialisation with the
high level AG header read functions. This largely replaces the
xfs_mount/agno pair that is passed to all these functions with a
perag, and in most places we already have a perag ready to pass in.
There are a few places where perags need to be grabbed before
reading the AG header buffers - some of these will need to be driven
to higher layers to ensure we can run operations on AGs without
getting stuck part way through waiting on a perag reference.

The latter section of this patchset moves some of the AG geometry
information from the xfs_mount to the xfs_perag, and starts
converting code that requires geometry validation to use a perag
instead of a mount and having to extract the AGNO from the object
location. This also allows us to store the AG size in the perag and
then we can stop having to compare the agno against sb_agcount to
determine if the AG is the last AG and so has a runt size. This
greatly simplifies some of the type validity checking we do and
substantially reduces the CPU overhead of type validity checking. It
also cuts over 1.2kB out of the binary size.

xfs: Pre-calculate per-AG agino geometry

There is a lot of overhead in functions like xfs_verify_agino() that
repeatedly calculate the geometry limits of an AG. These can be
pre-calculated as they are static and the verification context has
a per-ag context it can quickly reference.

In the case of xfs_verify_agino(), we now always have a perag
context handy, so we can store the minimum and maximum agino values
in the AG in the perag. This means we don't have to calculate
it on every call and it can be inlined in callers if we move it
to xfs_ag.h.

xfs_verify_agino_or_null() gets the same perag treatment.

xfs_agino_range() is moved to xfs_ag.c as it's not really a type
function, and it's use is largely restricted as the first and last
aginos can be grabbed straight from the perag in most cases.

Note that we leave the original xfs_verify_agino in place in
xfs_types.c as a static function as other callers in that file do
not have per-ag contexts so still need to go the long way. It's been
renamed to xfs_verify_agno_agino() to indicate it takes both an agno
and an agino to differentiate it from new function.

xfs: Pre-calculate per-AG agbno geometry

There is a lot of overhead in functions like xfs_verify_agbno() that
repeatedly calculate the geometry limits of an AG. These can be
pre-calculated as they are static and the verification context has
a per-ag context it can quickly reference.

In the case of xfs_verify_agbno(), we now always have a perag
context handy, so we can store the AG length and the minimum valid
block in the AG in the perag. This means we don't have to calculate
it on every call and it can be inlined in callers if we move it
to xfs_ag.h.

Move xfs_ag_block_count() to xfs_ag.c because it's really a
per-ag function and not an XFS type function. We need a little
bit of rework that is specific to xfs_initialise_perag() to allow
growfs to calculate the new perag sizes before we've updated the
primary superblock during the grow (chicken/egg situation).

Note that we leave the original xfs_verify_agbno in place in
xfs_types.c as a static function as other callers in that file do
not have per-ag contexts so still need to go the long way. It's been
renamed to xfs_verify_agno_agbno() to indicate it takes both an agno
and an agbno to differentiate it from new function.

Future commits will make similar changes for other per-ag geometry
validation functions.

Further:

after 1482185 329588 572 1812345 1ba779 (TOTALS)

This rework reduces the binary size by ~820 bytes, indicating
that much less work is being done to bounds check the agbno values
against on per-ag geometry information.
