Revision 06eb4cc2e7ad1b32a3b2580eff772c29b53a2cc6 authored by Linus Torvalds on 21 May 2014, 09:36:40 UTC, committed by Linus Torvalds on 21 May 2014, 09:36:40 UTC
Pull more cgroup fixes from Tejun Heo: "Three more patches to fix cgroup_freezer breakage due to the recent cgroup internal locking changes - an operation cgroup_freezer was using now requires sleepable context and cgroup_freezer was invoking that while holding a spin lock. cgroup_freezer was using an overly elaborate hierarchical locking scheme. While it's possible to convert the hierarchical spinlocks directly to mutexes, this patch simplifies the overall locking so that it uses a global mutex. This has the added benefit of avoiding iterating potentially huge number of tasks under a spinlock. While the patch is on the larger side in the devel cycle, the changes made are mostly straight-forward and the locking logic is a lot simpler afterwards" * 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: fix rcu_read_lock() leak in update_if_frozen() cgroup_freezer: replace freezer->lock with freezer_mutex cgroup: introduce task_css_is_root()
