Subject: ocfs2: free vol_label in ocfs2_delete_osb()
X-Git-Tag: v3.17-rc7~9^2~8
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=f13a568e5a787f3980f3bd00ba9dd0b78a734129;p=cascardo%2Flinux.git

ocfs2: free vol_label in ocfs2_delete_osb()

osb->vol_label is malloced in ocfs2_initialize_super but not freed if
error occurs or during umount, thus causing a memory leak.
