The patch titled Subject: ocfs2: move the mlog from the spinlock to outside has been removed from the -mm tree. Its filename was ocfs2-move-the-mlog-from-the-spinlock-to-outside.patch This patch was dropped because it was withdrawn ------------------------------------------------------ From: Shuning Zhang <sunny.s.zhang@xxxxxxxxxx> Subject: ocfs2: move the mlog from the spinlock to outside There is a potential task of deadlock. Because the mask is 0, the deadlock does not occur now. But There is a potential task. If someone change the mask of mlog, but forget to modify the order of the mlog and spin_unlock, There will be a potential deadlock.So I move the mlog from the spinlock to outsize.
