There were two just alike, making it hard maybe to tell which one
you were looking at in syslog... so I changed it a little by adding
some extra interesting tidbits to it...

Previously, it would update a live inode. This was fixed, but it did not
ever check that the inode attributes in the dcache are correct. This
checks all inode attributes and rejects any that are not correct, which
causes a lookup and thus a new getattr.
Perhaps inode_operations->permission should replace or augment some of
this.
There is no actual caching, and this does a rather excessive amount of
network operations back to the filesystem server.

* make op_release() decrement and free if zero (i.e. old put_op()
has become that).
* mark when submitter has given up waiting; from that point nobody
else can move between the lists, change state, etc.

and *always* give it up in the end

Orangefs: merge with V4.4
Merge tag 'v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into current
Linux 4.4
Until now, orangefs_devreq_write_iter has just been a wrapper for
the old-fashioned orangefs_devreq_writev... linux would call
.write_iter with "struct kiocb *iocb" and "struct iov_iter *iter"
and .write_iter would just:
return pvfs2_devreq_writev(iocb->ki_filp,
iter->iov,
iter->nr_segs,
&iocb->ki_pos);

We have found a BUG on res->migration_pending when migrating lock
resources. The situation is as follows.
dlm_mark_lockres_migration
res->migration_pending = 1;
__dlm_lockres_reserve_ast
dlm_lockres_release_ast returns with res->migration_pending remains
because other threads reserve asts
wait dlm_migration_can_proceed returns 1
>>>>>>> o2hb found that target goes down and remove target
from domain_map
dlm_migration_can_proceed returns 1
dlm_mark_lockres_migrating returns -ESHOTDOWN with
res->migration_pending still remains.
When reentering dlm_mark_lockres_migrating(), it will trigger the BUG_ON
with res->migration_pending. So clear migration_pending when target is
down.

When resizing, it firstly extends the last gd. Once it should backup
super in the gd, it calculates new backup super and update the
corresponding value.
But it currently doesn't consider the situation that the backup super is
already done. And in this case, it still sets the bit in gd bitmap and
then decrease from bg_free_bits_count, which leads to a corrupted gd and
trigger the BUG in ocfs2_block_group_set_bits:
BUG_ON(le16_to_cpu(bg->bg_free_bits_count) < num_bits);
So check whether the backup super is done and then do the updates.

so nothing was ever inlined anyway.
