Omar Sandoval e1ceceb494 xfs: don't check for AG deadlock for realtime files in bunmapi ... commit 69ffe5960d upstream. Commit 5b094d6dac ("xfs: fix multi-AG deadlock in xfs_bunmapi") added a check in __xfs_bunmapi() to stop early if we would touch multiple AGs in the wrong order. However, this check isn't applicable for realtime files. In most cases, it just makes us do unnecessary commits. However, without the fix from the previous commit ("xfs: fix realtime file data space leak"), if the last and second-to-last extents also happen to have different "AG numbers", then the break actually causes __xfs_bunmapi() to return without making any progress, which sends xfs_itruncate_extents_flags() into an infinite loop.
