The patch titled Subject: ocfs2: fix NULL dereference for moving extents has been removed from the -mm tree. Its filename was ocfs2-fix-null-dereference-for-moving-extents.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Subject: ocfs2: fix NULL dereference for moving extents We can't dereference "bg" before it has been assigned. GCC should have warned about this but "bg" was initialized to NULL. I've fixed that as well.
