Only failure that get_state_failrec can get is if there is no failure
for the given address. There is no reason why the function should return
a status code and use a separate parameter for returning the actual

a pointer and return ERR_PTR value in case of errors.

When syncing the log, we used to update the log root tree without holding
neither the log_mutex of the subvolume root nor the log_mutex of log root
tree.
We used to have two critical sections delimited by the log_mutex of the
log root tree, so in the first one we incremented the log_writers of the
log root tree and on the second one we decremented it and waited for the
log_writers counter to go down to zero. This was because the update of
the log root tree happened between the two critical sections.
The use of two critical sections allowed a little bit more of parallelism
and required the use of the log_writers counter, necessary to make sure
we didn't miss any log root tree update when we have multiple tasks trying
to sync the log in parallel.
However after commit 06989c799f ("Btrfs: fix race updating log root
item during fsync") the log root tree update was moved into a critical
section delimited by the subvolume's log_mutex. Later another commit
moved the log tree update from that critical section into the second
critical section delimited by the log_mutex of the log root tree. Both
commits addressed different bugs.
The end result is that the first critical section delimited by the
log_mutex of the log root tree became pointless, since there's nothing
done between it and the second critical section, we just have an unlock
of the log_mutex followed by a lock operation. This means we can merge
both critical sections, as the first one does almost nothing now, and we
can stop using the log_writers counter of the log root tree, which was
incremented in the first critical section and decremented in the second
criticial section, used to make sure no one in the second critical section
started writeback of the log root tree before some other task updated it.
So just remove the mutex_unlock() followed by mutex_lock() of the log root
tree, as well as the use of the log_writers counter for the log root tree.
This patch is part of a series that has the following patches:

We are incrementing the log_batch atomic counter of the root log tree but
we never use that counter, it's used only for the log trees of subvolume
roots. We started doing it when we moved the log_batch and log_write
counters from the global, per fs, btrfs_fs_info structure, into the
btrfs_root structure in commit 7237f18336 ("Btrfs: fix tree logs

So just stop doing it for the log root tree and add a comment over the
field declaration so inform it's used only for log trees of subvolume
roots.

When logging an inode we are committing its delayed items if either the
inode is a directory or if it is a new inode, created in the current
transaction.
We need to do it for directories, since new directory indexes are stored
as delayed items of the inode and when logging a directory we need to be
able to access all indexes from the fs/subvolume tree in order to figure
out which index ranges need to be logged.
However for new inodes that are not directories, we do not need to do it
because the only type of delayed item they can have is the inode item, and
we are guaranteed to always log an up to date version of the inode item:
*) for a full fsync we do it by committing the delayed inode and then
copying the item from the fs/subvolume tree with
copy_inode_items_to_log();
*) for a fast fsync we always log the inode item based on the contents of
the in-memory struct btrfs_inode. We guarantee this is always done since
commit e4545de5b0 ("Btrfs: fix fsync data loss after append write").
So stop running delayed items for a new inodes that are not directories,
since that forces committing the delayed inode into the fs/subvolume tree,
wasting time and adding contention to the tree when a full fsync is not
required. We will only do it in case a fast fsync is needed.

Commit 2c2c452b0c ("Btrfs: fix fsync when extend references are added
to an inode") forced a commit of the delayed inode when logging an inode
in order to ensure we would end up logging the inode item during a full
fsync. By committing the delayed inode, we updated the inode item in the
fs/subvolume tree and then later when copying items from leafs modified in
the current transaction into the log tree (with copy_inode_items_to_log())
we ended up copying the inode item from the fs/subvolume tree into the log
tree. Logging an up to date version of the inode item is required to make
sure at log replay time we get the link count fixup triggered among other
things (replay xattr deletes, etc). The test case generic/040 from fstests
exercises the bug which that commit fixed.
However for a fast fsync we don't need to commit the delayed inode because
we always log an up to date version of the inode item based on the struct
btrfs_inode we have in-memory. We started doing this for fast fsyncs since
commit e4545de5b0 ("Btrfs: fix fsync data loss after append write").

Although we can't enlarge the anonymous block device pool, at least we
can preallocate anon_dev for subvolume/snapshot in the first phase,
outside of transaction context and exactly at the moment the user calls
the creation ioctl.

The anonymous device pool is shared and its size is 1M. It's possible to
hit that limit if the subvolume deletion is not fast enough and the
subvolumes to be cleaned keep the ids allocated.

We can't avoid the anon device pool exhaustion but we can shorten the
time the id is attached to the subvolume root once the subvolume becomes

BTRFS: error (device sda1) in cleanup_transaction:1831: errno=-24 unknown
[CAUSE]
The error is EMFILE (Too many files open) and comes from the anonymous
block device allocation. The ids are in a shared pool of size 1<<20.
The ids are assigned to live subvolumes, ie. the root structure exists
in memory (eg. after creation or after the root appears in some path).
The pool could be exhausted if the numbers are not reclaimed fast
enough, after subvolume deletion or if other system component uses the
anon block devices.
[WORKAROUND]
Since it's not possible to completely solve the problem, we can only
minimize the time the id is allocated to a subvolume root.
Firstly, we can reduce the use of anon_dev by trees that are not
subvolume roots, like data reloc tree.
This patch will do extra check on root objectid, to skip roots that
don't need anon_dev. Currently it's only data reloc tree and orphan
roots.

btrfs_inode be the main inode struct.
