when o2hb detect a node down, it first set the dead node to recovery map
and create ocfs2rec which will replay journal for dead node. o2hb
thread then call dlm_do_local_recovery_cleanup() to delete the lock for
dead node. After the lock of dead node is gone, locks for other nodes
can be granted and may modify the meta data without replaying journal of
the dead node. The detail is described as follows.
N1 N2 N3(master)
modify the extent tree of
inode, and commit
dirty metadata to journal,
then goes down.
o2hb thread detects
N1 goes down, set
recovery map and
delete the lock of N1.
dlm_thread flush ast
for the lock of N2.
do not detect the death
of N1, so recovery map is
empty.
read inode from disk
without replaying
the journal of N1 and
modify the extent tree
of the inode that N1
had modified.
ocfs2rec recover the
journal of N1.
The modification of N2
is lost.
The modification of N1 and N2 are not serial, and it will lead to
read-only file system. We can set recovery_waiting flag to the lock
resource after delete the lock for dead node to prevent other node from
getting the lock before dlm recovery. After dlm recovery, the recovery
map on N2 is not empty, ocfs2_inode_lock_full_nested() will wait for ocfs2
recovery.

DROPPING_REF state
If master migrate this lock resource to node when it happened to purge
it, a new lock resource will be created and inserted into hash list. If
then master goes down, the lock resource being purged is recovered, so
there exist two lock resource with different owner. So return error to
master if the lock resource is in DROPPING state, master will retry to
migrate this lock resource.

BUG if the lockres is $RECOVERY
This series of patches add a new message to keep the order of set and
clear. Other nodes can purge the lock resource only after the refmap bit
on master is cleared.
This patch is to add DEREF_DONE message and corresponding handler. Node
can purge the lock resource after receiving this message. As a new

This patch basically reverts a very old patch from 2008,
7a9f53b3c1875bef22ad4588e818bc046ef183da, with the title
"Alternate gfs2_iget to avoid looking up inodes being freed".
The original patch was designed to avoid a deadlock caused by lock
ordering with try_rgrp_unlink. The patch forced the function to not
find inodes that were being removed by VFS. The problem is, that
made it impossible for nodes to delete their own unlinked dinodes
after a certain point in time, because the inode needed was not found
by this filtering process. There is no longer a need for the patch,
since function try_rgrp_unlink no longer locks the inode: All it does
is queue the glock onto the delete work_queue, so there should be no
more deadlock.

The fsx test in xfstests was failing because it was using direct IO
writes which were using a bad calculation. It was using
loff_t lstart = offset & (PAGE_CACHE_SIZE - 1); when it should be
loff_t lstart = offset & ~(PAGE_CACHE_SIZE - 1);
Thus, the write at offset 0x67e00 was calculating lstart to be
0xe00, the address of our corruption. Instead, it should have been
0x67000. This patch fixes the calculation.

We get a bogus warning about a potential uninitialized variable
use in gfs2, because the compiler does not figure out that we
never use the leaf number if get_leaf_nr() returns an error:
fs/gfs2/dir.c: In function 'get_first_leaf':
fs/gfs2/dir.c:802:9: warning: 'leaf_no' may be used uninitialized in this function [-Wmaybe-uninitialized]

Changing the 'if (!error)' to 'if (!IS_ERR_VALUE(error))' is
sufficient to let gcc understand that this is exactly the same
condition as in IS_ERR() so it can optimize the code path enough
to understand it.

error = __xfs_trans_roll(tp, ip, &committed);

and we tested an uninitialized "committed" variable on the

calls to __xfs_trans_roll(), so just initialize committed inside

xfs_bmap_del_extent() handles extent removal from the in-core and
on-disk extent lists. When removing a delalloc range, it updates the
indirect block reservation appropriately based on the removal. It
currently enforces that the new indirect block reservation is less than
or equal to the original. This is normally the case in all situations
except for in certain cases when the removed range creates a hole in a
single delalloc extent, thus splitting a single delalloc extent in two.
It is possible with small enough extents to split an indlen==1 extent
into two such slightly smaller extents. This leaves one extent with 0
indirect blocks and leads to assert failures in other areas (e.g.,
xfs_bunmapi() if the extent happens to be removed).
Update the indlen distribution code to steal blocks from the deleted
extent, if necessary, to satisfy the worst case total indirect
reservation for the new extents. This is safe as the caller does not
update the fdblocks counters until the extent is removed. Blocks stolen
in this manner simply remain accounted as allocated, having ownership
transferred from the data extent to an indirect reservation.
As a precaution, fall back to the original reservation algorithm if the
new indlen requirement is not met and warn if we end up with extents
without any reservation at all to detect this more easily in the future.

xfs_bunmapi() currently updates the fdblocks counter, unreserves quota,
etc. before the extent is deleted by xfs_bmap_del_extent(). The function
has problems dividing up the indirect reserved blocks for scenarios
where a single delalloc extent is split in two. Particularly, there
aren't always enough blocks reserved for multiple extents in a single
extent reservation.
The solution to this problem is to allow the extent removal code to
steal from the deleted extent to meet indirect reservation requirements.
Move the block of code in xfs_bmapi() that updates the fdblocks counter
to after the call to xfs_bmap_del_extent() to allow the codepath to
update the extent record before the free blocks are accounted. Also,
reshuffle the code slightly so the delalloc accounting occurs near the
xfs_bmap_del_extent() call to provide context for the comments.

Add a DEBUG mode-only sysfs knob to enable forced buffered write
failure. An additional side effect of this mode is brute force killing
of delayed allocation blocks in the range of the write. The latter is
the prime motiviation behind this patch, as userspace test
infrastructure requires a reliable mechanism to create and split
delalloc extents without causing extent conversion.
Certain fallocate operations (i.e., zero range) were used for this in
the past, but the implementations have changed such that delalloc
extents are flushed and converted to real blocks, rendering the test
useless.

The 'reqs' member of fuse_io_priv serves two purposes. First is to track
the number of oustanding async requests to the server and to signal that
the io request is completed. The second is to be a reference count on the
structure to know when it can be freed.
For sync io requests these purposes can be at odds. fuse_direct_IO() wants
to block until the request is done, and since the signal is sent when
'reqs' reaches 0 it cannot keep a reference to the object. Yet it needs to
use the object after the userspace server has completed processing
requests. This leads to some handshaking and special casing that it
needlessly complicated and responsible for at least one race condition.
It's much cleaner and safer to maintain a separate reference count for the
object lifecycle and to let 'reqs' just be a count of outstanding requests
to the userspace server. Then we can know for sure when it is safe to free
the object without any handshaking or special cases.
The catch here is that most of the time these objects are stack allocated
and should not be freed. Initializing these objects with a single reference
that is never released prevents accidental attempts to free the objects.

There's a race in fuse_direct_IO(), whereby is_sync_kiocb() is called on an
iocb that could have been freed if async io has already completed. The fix
in this case is simple and obvious: cache the result before starting io.
