Subject[PATCH] jbd: Silence warnings about non-uptodate buffers
Date
When underlying block device becomes unavailable (e.g. someone pulling an
USB stick from under us), kernel produces warning about non-uptodate buffer
(superblock) being marked dirty. Silence these warnings by making buffer
uptodate before marking it dirty.
