From: Filipe Manana <fdmanana@suse.com>
commit 0c0fe3b0fa45082cd752553fdb3a4b42503a118e upstream.
While doing some tests I ran into an hang on an extent buffer's rwlock
that produced the following trace:

This happens because in the code path executed by the inode_paths ioctl we
end up nesting two calls to read lock a leaf's rwlock when after the first
call to read_lock() and before the second call to read_lock(), another
task (running the delayed items as part of a transaction commit) has
already called write_lock() against the leaf's rwlock. This situation is
illustrated by the following diagram:
Task A Task B
btrfs_ref_to_path() btrfs_commit_transaction()
read_lock(&eb->lock);
btrfs_run_delayed_items()
__btrfs_commit_inode_delayed_items()
__btrfs_update_delayed_inode()
btrfs_lookup_inode()
write_lock(&eb->lock);
--> task waits for lock
read_lock(&eb->lock);
--> makes this task hang
forever (and task B too
of course)
So fix this by avoiding doing the nested read lock, which is easily
avoidable. This issue does not happen if task B calls write_lock() after
task A does the second call to read_lock(), however there does not seem
to exist anything in the documentation that mentions what is the expected
behaviour for recursive locking of rwlocks (leaving the idea that doing
so is not a good usage of rwlocks).
Also, as a side effect necessary for this fix, make sure we do not
needlessly read lock extent buffers when the input path has skip_locking
set (used when called from send).
