Revision 10ddf64e420f7f6c1a871bfb4ff2de08faef8235 authored by Darrick J. Wong on 14 December 2017, 23:46:05 UTC, committed by Darrick J. Wong on 21 December 2017, 16:47:32 UTC
When we're remounting the filesystem readonly, remove all CoW preallocations prior to going ro. If the fs goes down after the ro remount, we never clean up the staging extents, which means xfs_check will trip over them on a subsequent run. Practically speaking, the next mount will clean them up too, so this is unlikely to be seen. Since we shut down the cowblocks cleaner on remount-ro, we also have to make sure we start it back up if/when we remount-rw. Found by adding clonerange to fsstress and running xfs/017.
