Josef Bacik d98b5032c9 btrfs: fix deadlock with fsync+fiemap+transaction commit ... commit bf7ba8ee75 upstream. We are hitting the following deadlock in production occasionally Task 1 Task 2 Task 3 Task 4 Task 5 fsync(A) start trans start commit falloc(A) lock 5m-10m start trans wait for commit fiemap(A) lock 0-10m wait for 5m-10m (have 0-5m locked) have btrfs_need_log_full_commit !full_sync wait_ordered_extents finish_ordered_io(A) lock 0-5m DEADLOCK We have an existing dependency of file extent lock -> transaction. However in fsync if we tried to do the fast logging, but then had to fall back to committing the transaction, we will be forced to call btrfs_wait_ordered_range() to make sure all of our extents are updated. This creates a dependency of transaction -> file extent lock, because btrfs_finish_ordered_io() will need to take the file extent lock in order to run the ordered extents. Fix this by stopping the transaction if we have to do the full commit and we attempted to do the fast logging. Then attach to the transaction and commit it if we need to.
