From b4f48b6363c81ca743ef46943ef23fd72e60f679 Mon Sep 17 00:00:00 2001 From: Paul Menage Date: Thu, 18 Oct 2007 23:39:33 -0700 Subject: Task Control Groups: add fork()/exit() hooks This adds the necessary hooks to the fork() and exit() paths to ensure that new children inherit their parent's cgroup assignments, and that exiting processes release reference counts on their cgroups.
