From 59b8e85c26e77d236ebdd61866ffc5e69c5f531d Mon Sep 17 00:00:00 2001 From: Kamezawa Hiroyuki Date: Tue, 31 Jul 2012 16:42:42 -0700 Subject: [PATCH] memcg: remove check for signal_pending() during rmdir() After bf544fdc241da8 "memcg: move charges to root cgroup if use_hierarchy=0 in mem_cgroup_move_hugetlb_parent()", no memory reclaim will occur when removing a memory cgroup. If -EINTR is returned here, cgroup will show a warning. We don't need to handle any user interruption signal. Remove this.
