  - btrfs: fix deadlock between quota disable and qgroup rescan worker Quota disable ioctl starts a     transaction before waiting for the qgroup rescan worker completes. However, this wait can be infinite and     results in deadlock because of circular dependency among the quota disable ioctl, the qgroup rescan worker     and the other task with transaction such as block group relocation task. The deadlock happens with the     steps following: 1) Task A calls ioctl to disable quota. It starts a transaction and waits for qgroup     rescan worker completes. 2) Task B such as block group relocation task starts a transaction and joins to     the transaction that task A started. Then task B commits to the transaction. In this commit, task B waits     for a commit by task A. 3) Task C as the qgroup rescan worker starts its job and starts a transaction. In     this transaction start, task C waits for completion of the transaction that task A started and task B     committed. This deadlock was found with fstests test case btrfs/115 and a zoned null_blk device. The test     case enables and disables quota, and the block group reclaim was triggered during the quota disable by     chance. The deadlock was also observed by running quota enable and disable in parallel with 'btrfs     balance' command on regular null_blk devices.
