The patch titled kernel/user.c: fix freeing user_struct in user cache has been removed from the -mm tree. Its filename was kernel-userc-fix-freeing-user_struct-in-user-cache.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: kernel/user.c: fix freeing user_struct in user cache From: Hillf Danton <dhillf@xxxxxxxxx> When racing on adding into user cache, the new allocated from mm slab is freed without putting user namespace. Since the user namespace is already operated by getting, putting has to be issued.
