[PATCH] fix uidhash_lock <-> RCU deadlock
RCU task-struct freeing can call free_uid(), which is taking uidhash_lock - while other users of uidhash_lock are softirq-unsafe. The fix is to always take the uidhash_spinlock in a softirq-safe manner. Signed-off-by: Ingo Molnar <mingo@elte.hu> Acked-by: Paul E.
