[Ocfs2-tools-devel] [PATCH] fsck.ocfs2: warn and return if ocfs2_malloc fails in walk_cwd

[piaojun]

In walk_cwd, we should check return code in case of ocfs2_malloc fails.
Otherwise, segment fault will happen.

Fixes: 6b689d45289d ("fsck.ocfs2: dynamically allocate ocfs2_dir_entry
for long filenames")
