The patch titled memcg: remove pointless next_mz nullification in mem_cgroup_soft_limit_reclaim() has been removed from the -mm tree. Its filename was memcg-remove-pointless-next_mz-nullification-in-mem_cgroup_soft_limit_reclaim.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: memcg: remove pointless next_mz nullification in mem_cgroup_soft_limit_reclaim() From: Michal Hocko <mhocko@xxxxxxx> next_mz is assigned to NULL if __mem_cgroup_largest_soft_limit_node selects the same mz. This doesn't make much sense as we assign to the variable right in the next loop. Compiler will probably optimize this out but it is little bit confusing for the code reading.
