The quilt patch titled
     Subject: ocfs2: ocfs2_initialize_super does cleanup job before return error
has been removed from the -mm tree.  Its filename was
     ocfs2-ocfs2_initialize_super-does-cleanup-job-before-return-error.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
