Subject: [PATCH] e2fsprogs: fix freeing bitmap in allocation error path
Date: Mon, 21 Mar 2011 11:13:41 +0100 [thread overview]
Message-ID: <1300702421-4774-1-git-send-email-lczerner@redhat.com> (raw)
In ext2fs_alloc_generic_bmap() error path, when new bitmap allocation
fails ext2fs_generic_bitmap should be freed, however in current state it
first frees ext2fs_generic_bitmap and then
ext2fs_generic_bitmap->description which is wrong. This commit fix the
free ordering.
