I believe the patch is fine (it already has my reviewed-by).

Except: I am not sure about -stable. At least, this patch should
not go into the <2.6.35 kernels, it relies on misc changes which
changed the scope of task->signal. Before 2.6.35 almost any user
of ->cred_guard_mutex can race with exit and hit ->signal == NULL.

Oleg.
