gfs2: Replace gfs2_glock_queue_put with gfs2_glock_put_async

[ Upstream commit ee2be7d7c7f32783f60ee5fe59b91548a4571f10 ]

Function gfs2_glock_queue_put() puts a glock reference by enqueuing
glock work instead of putting the reference directly. This ensures that
the operation won't sleep, but it is costly and really only necessary
when putting the final glock reference. Replace it with a new
gfs2_glock_put_async() function that only queues glock work when putting
the last glock reference.

gfs2: Fix NULL pointer dereference in gfs2_log_flush

[ Upstream commit 35264909e9d1973ab9aaa2a1b07cda70f12bb828 ]

In gfs2_jindex_free(), set sdp->sd_jdesc to NULL under the log flush
lock to provide exclusion against gfs2_log_flush().

In gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before
dereferencing it. Otherwise, we could run into a NULL pointer
dereference when outstanding glock work races with an unmount
(glock_work_func -> run_queue -> do_xmote -> inode_go_sync ->
gfs2_log_flush).

Pull gfs2 updates from Andreas Gruenbacher:

- Fix a glock state (non-)transition bug when a dlm request times out
and is canceled, and we have locking requests that can now be granted
immediately

- Various fixes and cleanups in how the logd and quotad daemons are
woken up and terminated

- Fix several bugs in the quota data reference counting and shrinking.
Free quota data objects synchronously in put_super() instead of
letting call_rcu() run wild

- Make sure not to deallocate quota data during a withdraw; rather,
defer quota data deallocation to put_super(). Withdraws can happen in
contexts in which callers on the stack are holding quota data
references

- Many minor quota fixes and cleanups by Bob

- Update the the mailing list address for gfs2 and dlm. (It's the same
list for both and we are moving it to gfs2@lists.linux.dev)

gfs2: low-memory forced flush fixes

First, function gfs2_ail_flush_reqd checks the SDF_FORCE_AIL_FLUSH flag
to determine if an AIL flush should be forced in low-memory situations.
However, it also immediately clears the flag, and when called repeatedly
as in function gfs2_logd, the flag will be lost. Fix that by pulling
the SDF_FORCE_AIL_FLUSH flag check out of gfs2_ail_flush_reqd.

Second, function gfs2_writepages sets the SDF_FORCE_AIL_FLUSH flag
whether or not enough pages were written. If enough pages could be
written, flushing the AIL is unnecessary, though.

Third, gfs2_writepages doesn't wake up logd after setting the
SDF_FORCE_AIL_FLUSH flag, so it can take a long time for logd to react.
It would be preferable to wake up logd, but that hurts the performance
of some workloads and we don't quite understand why so far, so don't
wake up logd so far.

gfs2: Rework freeze / thaw logic

So far, at mount time, gfs2 would take the freeze glock in shared mode
and then immediately drop it again, turning it into a cached glock that
can be reclaimed at any time. To freeze the filesystem cluster-wide,
the node initiating the freeze would take the freeze glock in exclusive
mode, which would cause the freeze glock's freeze_go_sync() callback to
run on each node. There, gfs2 would freeze the filesystem and schedule
gfs2_freeze_func() to run. gfs2_freeze_func() would re-acquire the
freeze glock in shared mode, thaw the filesystem, and drop the freeze
glock again. The initiating node would keep the freeze glock held in
exclusive mode. To thaw the filesystem, the initiating node would drop
the freeze glock again, which would allow gfs2_freeze_func() to resume
on all nodes, leaving the filesystem in the thawed state.

It turns out that in freeze_go_sync(), we cannot reliably and safely
freeze the filesystem. This is primarily because the final unmount of a
filesystem takes a write lock on the s_umount rw semaphore before
calling into gfs2_put_super(), and freeze_go_sync() needs to call
freeze_super() which also takes a write lock on the same semaphore,
causing a deadlock. We could work around this by trying to take an
active reference on the super block first, which would prevent unmount
from running at the same time. But that can fail, and freeze_go_sync()
isn't actually allowed to fail.

To get around this, this patch changes the freeze glock locking scheme
as follows:

At mount time, each node takes the freeze glock in shared mode. To
freeze a filesystem, the initiating node first freezes the filesystem
locally and then drops and re-acquires the freeze glock in exclusive
mode. All other nodes notice that there is contention on the freeze
glock in their go_callback callbacks, and they schedule
gfs2_freeze_func() to run. There, they freeze the filesystem locally
and drop and re-acquire the freeze glock before re-thawing the
filesystem. This is happening outside of the glock state engine, so
there, we are allowed to fail.

From a cluster point of view, taking and immediately dropping a glock is
indistinguishable from taking the glock and only dropping it upon
contention, so this new scheme is compatible with the old one.

Thanks to Li Dong <lidong@vivo.com> for reporting a locking bug in
gfs2_freeze_func() in a previous version of this commit.
