Thank you!
Hi Linus, Please pull this branch for 5.16-rc4 that fixes a race between a readonly remount process and other processes that hold a file IOLOCK on files that previously experienced copy on write, that could result in severe filesystem corruption if the filesystem is then remounted rw. I think this is fairly rare (since the only reliable reproducer I have that fits the second criteria is the experimental xfs_scrub program), but the race is clear, so we still need to fix this. The branch merges cleanly against upstream as of a few minutes ago. Please let me know if anything else strange happens during the merge process. --D The following changes since commit e445976537ad139162980bee015b7364e5b64fff: xfs: remove incorrect ASSERT in xfs_rename (2021-12-01 17:27:48 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-5.16-fixes-3 for you to fetch changes up to 089558bc7ba785c03815a49c89e28ad9b8de51f9: xfs: remove all COW fork extents when remounting readonly (2021-12-07 10:17:29 -0800) ---------------------------------------------------------------- Fixes for 5.16-rc4: - Fix a data corruption vector that can result from the ro remount process failing to clear all speculative preallocations from files and the rw remount process not noticing the incomplete cleanup. ---------------------------------------------------------------- Darrick J.
