Revision 0261d6886eb5822867a5310dc1e4479b940a1942 authored by Jens Axboe on 30 October 2006, 18:07:48 UTC, committed by Linus Torvalds on 30 October 2006, 18:21:58 UTC
If cfq_set_request() is called for a new process AND a non-fs io request (so that __GFP_WAIT may not be set), cfq_cic_link() may use spin_lock_irq() and spin_unlock_irq() with interrupts already disabled. Fix is to always use irq safe locking in cfq_cic_link() Acked-By: Arjan van de Ven <arjan@linux.intel.com> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
