This pull request contains three fixes. Two are reverts of task_lock() removal in cgroup fork path. The optimizations incorrectly assumed that threadgroup_lock can protect process forks (as opposed to thread creations) too. Further cleanup of cgroup fork path is scheduled. The third fixes cgroup emptiness notification loss. Please pull from the following git branch to receive the above changes. git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-3.7-fixes for you to fetch changes up to d87838321124061f6c935069d97f37010fa417e6: Revert "cgroup: Remove task_lock() from cgroup_post_fork()" (2012-10-19 14:09:35 -0700) ---------------------------------------------------------------- Daisuke Nishimura (1): cgroup: notify_on_release may not be triggered in some cases Tejun Heo (2): Revert "cgroup: Drop task_lock(parent) on cgroup_fork()" Revert "cgroup: Remove task_lock() from cgroup_post_fork()" kernel/cgroup.c | 41 ++++++++++------------------------------- 1 file changed, 10 insertions(+), 31 deletions(-) Thanks. -- tejun
