Revision 0f64b247e63ac8c214efa6725366b42563ab138c authored by Nicolas Pitre on 12 August 2015, 15:45:02 UTC, committed by Russell King on 18 August 2015, 12:59:59 UTC
The mmap semaphore should not be taken when page faults are disabled. Since pagefault_disable() no longer disables preemption, we now need to use faulthandler_disabled() in place of in_atomic().
