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, and a patch adding a helper to optimize the code structure.
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().
The 3rd patch adds a xfs_buf copy helper to optimize the code structure.
Changes of v2:
- 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.
Changes of v3:
- fix code style, and
- add a new patch which does xfs_buf memcpy in a helper.
Thanks,
Jiachen
