[PATCH 0/2] nilfs2: protect busy buffer heads from being force-cleared

Posted by Ryusuke Konishi 11 months, 2 weeks ago

Hi Andrew, please queue this series for the next cycle.

This series fixes the buffer head state inconsistency issues reported by
syzbot that occurs when the filesystem is corrupted and falls back to
read-only, and the associated buffer head use-after-free issue.

Thanks,
Ryusuke Konishi
