6.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana fdmanana@suse.com
commit 2a5898c4aac67494c2f0f7fe38373c95c371c930 upstream.
If we failed walking a log tree during replay, we have a missing transaction abort to prevent committing a transaction where we didn't fully replay all the changes from a log tree and therefore can leave the respective subvolume tree in some inconsistent state. So add the missing transaction abort.
