The ->writepage() and ->writepages() operations are supposed to write
entire pages.  However, on filesystems with a block size smaller than
PAGE_SIZE, __gfs2_jdata_writepage() only adds the first block to the
current transaction instead of adding the entire page.  Fix that.

In gfs2_make_fs_rw(), make sure to call gfs2_consist() to report an
inconsistency and mark the filesystem as withdrawn when

At the end of gfs2_make_fs_rw(), when we discover that the filesystem
has been withdrawn, make sure we report an error.  This also replaces
the gfs2_withdrawn() check after gfs2_find_jhead().

This reverts commit 970343cd ("GFS2: free disk inode which is
deleted by remote node -V2").

The original intent behind commit 970343cd was to cull dentries when a
remote node requests to demote an iopen glock, which happens when the
remote node tries to delete the inode.  This is now handled by
gfs2_try_evict(), which is called via iopen_go_callback() ->
gfs2_queue_try_to_evict().

In gfs2_kill_sb(), flush the delete work queue after setting the

evict_inodes() call.

With that, function gfs2_make_fs_ro() now calls gfs2_flush_delete_work()
after the workqueue has been destroyed.  Skip that by checking for the
presence of the SDF_DEACTIVATING flag.

Function gfs2_clear_rgrpd() is called during unmount to free all rgrps
and their sub-objects. If the rgrp glock is held (e.g. in SH) it calls
gfs2_glock_cb() to unlock, then calls flush_delayed_work() to make
sure any glock work is finished. However, there is a race with other
cluster nodes who may request the rgrp glock in another mode (say, EX).

Func gfs2_clear_rgrpd() calls glock_clear_object() which sets gl_object
to NULL but that's done without holding the gl_lockref spin_lock.
While the lock is not held Another node's demote request can cause the
state machine to run again, and since the gl_lockref is released in
do_xmote, the second process's call to do_xmote can call go_inval
(rgrp_go_inval) after the gl_object has been cleared, which results in
NULL pointer reference of the rgrp glock's gl_object.

Other go_inval glops functions don't require the gl_object to exist, as
evidenced by function inode_go_inval() which explicitly checks for if
(ip) before referencing gl_object. This patch does the same thing
for rgrp glocks. Both the go_inval and go_sync ops are patched to check
the existence of gl_object (rgd) before trying to dereference it.

Function delete_work_func() is used for two purposes:

 * to immediately try to evict the glock's inode, and

 * to verify after a little while that the inode has been deleted as
   expected, and didn't just get skipped.

These two operations are not separated very well, so introduce two new
glock flags to improved that.  Split gfs2_queue_delete_work() into
gfs2_queue_try_to_evict and gfs2_queue_verify_evict().

Get rid of the GLF_PENDING_DELETE glock flag introduced by commit
a0e3cc65 ("gfs2: Turn gl_delete into a delayed work").  The only use
of that flag is to prevent the iopen glock from being demoted (i.e.,
unlocked) while delete work is pending.  It turns out that demoting the
iopen glock while delete work is pending is perfectly fine; we only need
to make sure that the glock isn't being freed while still in use.  This
is ensured by the previous patch because delete_work_func() owns a
reference while the work is queued or running.

With these changes, gfs2_queue_delete_work() no longer takes the glock
spin lock, so we can use it in iopen_go_callback() instead of
open-coding it there.

In __gfs2_glock_put(), remove the glock from the lru list *after*
dropping the glock lock.  This prevents deadlocks against
gfs2_scan_glock_lru().

In gfs2_scan_glock_lru(), make sure that the glock's reference count is
zero before moving the glock to the dispose list.  This skips glocks
that are marked dead as well as glocks that are still in use.
Additionally, switch to spin_trylock() as we already do in
gfs2_dispose_glock_lru(); this alone would also be enough to prevent
deadlocks against __gfs2_glock_put().

Improve the comment describing the inode and iopen glock interactions
and the glock poking related to inode evict.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>

Function glock_clear_object() checks if the specified glock is still
pointing at the right object and clears the gl_object pointer.  To
handle the case of incompletely constructed inodes, glock_clear_object()
also allows gl_object to be NULL.

However, in the teardown case, when iget_failed() is called and the
inode is removed from the inode hash, by the time we get to the
glock_clear_object() calls in gfs2_put_super() and its helpers, we don't
have exclusion against concurrent gfs2_inode_lookup() and
gfs2_create_inode() calls, and the inode and iopen glocks may already be
pointing at another inode, so the checks in glock_clear_object() are
incorrect.

To better handle this case, always completely disassociate an inode from
its glocks before tearing it down.  In addition, get rid of a duplicate
glock_clear_object() call in gfs2_evict_inode().  That way,
glock_clear_object() will only ever be called when the glock points at
the current inode, and the NULL check in glock_clear_object() can be
removed.

Pull gfs2 writepage fix from Andreas Gruenbacher:

 - Fix a regression introduced by commit "gfs2: stop using
   generic_writepages in gfs2_ail1_start_one".

  Revert "gfs2: stop using generic_writepages in gfs2_ail1_start_one"

Commit b2b0a5e9 switched from generic_writepages() to
filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to
replacing ->writepage() with ->writepages() and eventually eliminating
the former.  Function gfs2_ail1_start_one() is called from
gfs2_log_flush(), our main function for flushing the filesystem log.

Unfortunately, at least as implemented today, ->writepage() and
->writepages() are entirely different operations for journaled data
inodes: while the former creates and submits transactions covering the
data to be written, the latter flushes dirty buffers out to disk.

With gfs2_ail1_start_one() now calling ->writepages(), we end up
creating filesystem transactions while we are in the course of a log
flush, which immediately deadlocks on the sdp->sd_log_flush_lock
semaphore.

Work around that by going back to how things used to work before commit
b2b0a5e9 for now; figuring out a superior solution will take time we
don't have available right now.  However ...

Since the removal of generic_writepages() is imminent, open-code it
here.  We're already inside a blk_start_plug() ...  blk_finish_plug()
section here, so skip that part of the original generic_writepages().

We potentially have old hashes of the xattr names generated on systems
with signed 'char' types.  Now that everybody uses '-funsigned-char',
those hashes will no longer match.

This only happens if you use xattrs names that have the high bit set,
which probably doesn't happen in practice, but the xfstest generic/454
shows it.

Instead of adding a new "signed xattr hash filesystem" bit and having to
deal with all the possible combinations, just calculate the hash both
ways if the first one fails, and always generate new hashes with the
proper unsigned char version.

A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.

A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests.

Pull ACPI fixes from Rafael Wysocki:
 "These update the ACPICA entry in MAINTAINERS, add a backlight handling
  quirk and fix the ACPI PRM (platform runtime) mechanism support.

  Specifics:

   - Update the ACPICA development list address in MAINTAINERS to the
     new one that does not bounce (Rafael Wysocki)

   - Check whether EFI runtime is available when registering the ACPI
     PRM address space handler and when running it (Ard Biesheuvel)

   - Add backlight=native DMI quirk for Acer Aspire 4810T to the ACPI
     video driver (Hans de Goede)"
