From 39cc98f1f8aa949afeea89f424c7494b0785d7da Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Thu, 26 May 2011 16:25:28 -0700 Subject: [PATCH] memcg: remove pointless next_mz nullification in mem_cgroup_soft_limit_reclaim() 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.
