:---------------------------------------------
:krunner/2402 is trying to acquire lock:
: (l3_key){+.+...}, at: [<ffffffff81133172>] ____cache_alloc+0xab/0x212
:but task is already holding lock:
: (l3_key){+.+...}, at: [<ffffffff811325ae>] __cache_free+0x145/0x1e8
:other info that might help us debug this:
: Possible unsafe locking scenario:
:       CPU0
:       ----
:  lock(l3_key);
:  lock(l3_key);
: *** DEADLOCK ***
: May be due to missing lock nesting notation
