Greetings,
I got this lockdep warning and the first bad commit is
d206e09036d6201f90b2719484c8a59526c46125 ("Merge branch 'for-3.8' of
git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup")
[ 1.969480]
[ 1.969686] ======================================================
[ 1.970200] [ INFO: possible circular locking dependency detected ]
[ 1.970200] 3.7.0-05910-g6be35c7 #1 Not tainted
[ 1.970200] -------------------------------------------------------
[ 1.970200] swapper/0/1 is trying to acquire lock:
[ 1.970200] (cgroup_mutex){+.+...}, at: [<81068053>] cgroup_lock+0xf/0x11
[ 1.970200]
[ 1.970200] but task is already holding lock:
[ 1.970200] (cpu_hotplug.lock){+.+.+.}, at: [<8102674b>] cpu_hotplug_begin+0x1d/0x40
[ 1.970200]
[ 1.970200] which lock already depends on the new lock.
[ 1.970200]
[ 1.970200]
Thanks,
Fengguang

* [PATCH] memcg: don't register hotcpu notifier from ->css_alloc()

648bb56d07 ("cgroup: lock cgroup_mutex in cgroup_init_subsys()") made
cgroup_init_subsys() grab cgroup_mutex before invoking ->css_alloc()
for the root css. Because memcg registers hotcpu notifier from
->css_alloc() for the root css, this introduced circular locking
dependency between cgroup_mutex and cpu hotplug.
Fix it by moving hotcpu notifier registration to a subsys initcall.

* [PATCH] memcg: don't register hotcpu notifier from ->css_alloc()

648bb56d07 ("cgroup: lock cgroup_mutex in cgroup_init_subsys()") made
cgroup_init_subsys() grab cgroup_mutex before invoking ->css_alloc()
for the root css. Because memcg registers hotcpu notifier from
->css_alloc() for the root css, this introduced circular locking
dependency between cgroup_mutex and cpu hotplug.
Fix it by moving hotcpu notifier registration to a subsys initcall.

Hmm, we can move enable_swap_cgroup() and per-cpu memcg_stock
initialization here as well to make the css_alloc a bit cleaner.
mem_cgroup_soft_limit_tree_init with a trivial BUG_ON() on allocation
failure can go there as well.
I will do it.

Hmm, we can move enable_swap_cgroup() and per-cpu memcg_stock
initialization here as well to make the css_alloc a bit cleaner.
mem_cgroup_soft_limit_tree_init with a trivial BUG_ON() on allocation
failure can go there as well.
I will do it.

The thing was that cgroup_init() happens before any initcalls so
you'll end up with root css being set up before other stuff gets
initialized, which could be okay but a bit nasty. I'm wondering why
cgroup_init() has to happen so early. The cpu one is already taking
an early init path, but the rest doesn't seem to need such early init.
Anyways, yeap, no objection to cleaning up anyway which fits memcg.
We can deal with the whole init order thing later.
Thanks.
