Hi, Recently, our use-case ran into 2 bugs in case doing xfs_remove when the disk space is in-pressure, which may cause xfs shutdown and kernel crash in the xfs log recovery procedure. Here are 2 patches to fix the problem. The 1st patch fixes an uninitialized variable issue. The 2nd patch ensures the blkno in the xfs_buf is updated when doing xfs_da3_swap_lastblock(). Compared with the V1 patchset, this V2 patchset - directly set the *logflagsp value to make the code more robust in the 1st commit, - check xfs's crc-feature rather than magic in the 2nd commit, and - fixed code style and rebased onto the master branch. Thanks, Jiachen Jiachen Zhang (1): xfs: ensure logflagsp is initialized in xfs_bmap_del_extent_real Zhang Tianci (1): xfs: update dir3 leaf block metadata after swap fs/xfs/libxfs/xfs_bmap.c | 26 ++++++++++++++------------ fs/xfs/libxfs/xfs_da_btree.c | 11 ++++++++++- 2 files changed, 24 insertions(+), 13 deletions(-) -- 2.20.1
