Pull xfs updates from Chandan Babu:

- Chandan Babu will be taking over as the XFS release manager. He has
reviewed all the patches that are in this branch, though I'm signing
the branch one last time since I'm still technically maintainer. :P

- Create a maintainer entry profile for XFS in which we lay out the
various roles that I have played for many years. Aside from release
manager, the remaining roles are as yet unfilled.

- Start merging online repair -- we now have in-memory pageable memory
for staging btrees, a bunch of pending fixes, and we've started the
process of refactoring the scrub support code to support more of
repair. In particular, reaping of old blocks from damaged structures.

- Scrub the realtime summary file.

- Fix a bug where scrub's quota iteration only ever returned the root
dquot. Oooops.

- Fix some typos.

xfs: online scrubbing of realtime summary files

This patchset implements an online checker for the realtime summary
file. The first few changes are some general cleanups -- scrub should
get its own references to all inodes, and we also wrap the inode lock
functions so that we can standardize unlocking and releasing inodes that
are the focus of a scrub.

With that out of the way, we move on to constructing a shadow copy of
the rtsummary information from the rtbitmap, and compare the new copy
against the ondisk copy.

This has been running on the djcloud for years with no problems. Enjoy!

xfs: drain deferred work items when scrubbing [v24.5]

The design doc for XFS online fsck contains a long discussion of the
eventual consistency models in use for XFS metadata. In that chapter,
we note that it is possible for scrub to collide with a chain of
deferred space metadata updates, and proposes a lightweight solution:
The use of a pending-intents counter so that scrub can wait for the
system to drain all chains.

This patchset implements that scrub drain. The first patch implements
the basic mechanism, and the subsequent patches reduce the runtime
overhead by converting the implementation to use sloppy counters and
introducing jump labels to avoid walking into scrub hooks when it isn't
running. This last paradigm repeats elsewhere in this megaseries.

v23.1: make intent items take an active ref to the perag structure and
document why we bump and drop the intent counts when we do

xfs: minimize overhead of drain wakeups by using jump labels

To reduce the runtime overhead even further when online fsck isn't
running, use a static branch key to decide if we call wake_up on the
drain. For compilers that support jump labels, the call to wake_up is
replaced by a nop sled when nobody is waiting for intents to drain.

From my initial microbenchmarking, every transition of the static key
between the on and off states takes about 22000ns to complete; this is
paid entirely by the xfs_scrub process. When the static key is off
(which it should be when fsck isn't running), the nop sled adds an
overhead of approximately 0.36ns to runtime code. The post-atomic
lockless waiter check adds about 0.03ns, which is basically free.

For the few compilers that don't support jump labels, runtime code pays
the cost of calling wake_up on an empty waitqueue, which was observed to
be about 30ns. However, most architectures that have sufficient memory
and CPU capacity to run XFS also support jump labels, so this is not
much of a worry.
