Subject: ocfs2: do not put bh when buffer_uptodate failed
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f7cf4f5bfe073ad792ab49c04f247626b3e38db6;p=linux.git
ocfs2: do not put bh when buffer_uptodate failed
Do not put bh when buffer_uptodate failed in ocfs2_write_block and
ocfs2_write_super_or_backup, because it will put bh in b_end_io.
Otherwise it will hit a warning "VFS: brelse: Trying to free free
buffer".
