From e57d5cf2f894e3f2727f8cf74bed0bc81cae70c8 Mon Sep 17 00:00:00 2001 From: Rami Rosen Date: Tue, 16 Apr 2013 23:24:55 +0300 Subject: devcg: remove parent_cgroup. In devcgroup_css_alloc(), there is no longer need for parent_cgroup. bd2953ebbb("devcg: propagate local changes down the hierarchy") made the variable parent_cgroup redundant. This patch removes parent_cgroup from devcgroup_css_alloc().
