Hi Arnd, this commit:

commit 58374713c9dfb4d231f8c56cac089f6fbdedc2ec Author: Arnd Bergmann arnd@arndb.de Date:   Sat Jul 10 23:51:39 2010 +0200

drm: kill BKL from common code

moved the call to (inside drm_release) drm_lastclose inside dev->count_lock spinlock. drm_lastclose however takes dev->struct_mutex (now inside an atomic context):

I have a patch from Chris Wilson that I need to push to fix this, basically reducing the spin lock coverage, and relying on the global mutex to handle the open race.

Ok, thank you :)

Luca
