xfs: hoist freeing of rt data fork extent mappings

commit 6c664484337b37fa0cf6e958f4019623e30d40f7 upstream.

Currently, xfs_bmap_del_extent_real contains a bunch of code to convert
the physical extent of a data fork mapping for a realtime file into rt
extents and pass that to the rt extent freeing function. Since the
details of this aren't needed when CONFIG_XFS_REALTIME=n, move it to
xfs_rtbitmap.c to reduce code size when realtime isn't enabled.

This will (one day) enable realtime EFIs to reuse the same
unit-converting call with less code duplication.

Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Dave Chinner:
"This is a big update with lots of new code. The summary below them
all, so I'll just touch on teh higlights. The two main new features
are Large Extent Counts and Logged Attribute Replay - these are two
new foundational features that we are building more complex future
features on top of.

For upcoming functionality, we need to be able to store hundreds of
millions of xattrs per inode. The Large Extent Count feature removes
the limits that prevent this scale of xattr storage, and while we were
modifying the on disk extent count format we also increased the number
of data extents we support per inode from 2^32 to 2^47.

We also need to be able to modify xattrs as part of larger atomic
transactions rather than as standalone transactions. The Logged
Attribute Replay feature introduces the infrastructure that allows us
to use intents to record the attribute modifications in the journal
before we start them, hence allowing other atomic transactions to log
attribute modification intents and then defer the actual modification
to later. If we then crash, log recovery then guarantees that the
attribute is replayed in the context of the atomic transaction that
logged the intent.

A significant chunk of the commits in this merge are for the base
attribute replay functionality along with fixes, improvements and
cleanups related to this new functioanlity. Allison deserves a big
round of thanks for her ongoing work to get this functionality into
XFS.

There are also many other smaller changes and improvements, so overall
this is one of the bigger XFS merge requests in some time.

I will be following up next week with another smaller pull request -
we already have another round of fixes and improvements to the logged
attribute replay functionality just about ready to go. They'll soak
and test over the next week, and I'll send a pull request for them
near the end of the merge window.

Summary:

- support for printk message indexing.

- large extent counts to provide support for up to 2^47 data extents
and 2^32 attribute extents, allowing us to scale beyond 4 billion
data extents to billions of xattrs per inode.

- conversion of various flags fields to be consistently declared as
unsigned bit fields.

- improvements to realtime extent accounting and converts them to
per-cpu counters to match all the other block and inode accounting.

- reworks core log formatting code to reduce iterations, have a
shorter, cleaner fast path and generally be easier to understand
and maintain.

- improvements to rmap btree searches that reduce overhead by up to
30% resulting in xfs_scrub runtime reductions of 15%.

- improvements to reflink that remove the size limitations in
remapping operations and greatly reduce the size of transaction
reservations.

- reworks the minimum log size calculations to allow us to change
transaction reservations without changing the minimum supported log
size.

- removal of quota warning support as it has never been used on
Linux.

- intent whiteouts to allow us to cancel intents that are completed
entirely in memory rather than having use CPU and disk bandwidth
formatting and writing them into the journal when it is not
necessary. This makes rmap, reflink and extent freeing slightly
more efficient, but provides massive improvements for....

- Logged Attribute Replay feature support. This is a fundamental
change to the way we modify attributes, laying the foundation for
future integration of attribute modifications as part of other
atomic transactional operations the filesystem performs.

- Lots of cleanups and fixes for the logged attribute replay
functionality"

xfs: recalculate free rt extents after log recovery

I've been observing periodic corruption reports from xfs_scrub involving
the free rt extent counter (frextents) while running xfs/141. That test
uses an error injection knob to induce a torn write to the log, and an
arbitrary number of recovery mounts, frextents will count fewer free rt
extents than can be found the rtbitmap.

The root cause of the problem is a combination of the misuse of
sb_frextents in the incore mount to reflect both incore reservations
made by running transactions as well as the actual count of free rt
extents on disk. The following sequence can reproduce the undercount:

Thread 1 Thread 2
xfs_trans_alloc(rtextents=3)
xfs_mod_frextents(-3)
<blocks>
xfs_attr_set()
xfs_bmap_attr_addfork()
xfs_add_attr2()
xfs_log_sb()
xfs_sb_to_disk()
xfs_trans_commit()
<log flushed to disk>
<log goes down>

Note that thread 1 subtracts 3 from sb_frextents even though it never
commits to using that space. Thread 2 writes the undercounted value to
the ondisk superblock and logs it to the xattr transaction, which is
then flushed to disk. At next mount, log recovery will find the logged
superblock and write that back into the filesystem. At the end of log
recovery, we reread the superblock and install the recovered
undercounted frextents value into the incore superblock. From that
point on, we've effectively leaked thread 1's transaction reservation.

The correct fix for this is to separate the incore reservation from the
ondisk usage, but that's a matter for the next patch. Because the
kernel has been logging superblocks with undercounted frextents for a
very long time and we don't demand that sysadmins run xfs_repair after a
crash, fix the undercount by recomputing frextents after log recovery.

Gating this on log recovery is a reasonable balance (I think) between
correcting the problem and slowing down every mount attempt. Note that
xfs_repair will fix undercounted frextents.
