The patch titled memcgroup: fix spurious EBUSY on memory cgroup removal has been removed from the -mm tree. Its filename was memcgroup-fix-spurious-ebusy-on-memory-cgroup-removal.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: memcgroup: fix spurious EBUSY on memory cgroup removal From: YAMAMOTO Takashi <yamamoto@xxxxxxxxxxxxx> Call mm_free_cgroup earlier. Otherwise a reference due to lazy mm switching can prevent cgroup removal.
