Revision f53ae1dc3429529a58aa538e0a860d713c7079c3 authored by Oleg Nesterov on 15 June 2006, 16:12:02 UTC, committed by Linus Torvalds on 17 June 2006, 17:52:13 UTC
arm_timer() checks PF_EXITING to prevent BUG_ON(->exit_state) in run_posix_cpu_timers(). However, for some reason it does so only for CPUCLOCK_PERTHREAD case (which is imho wrong). Also, this check is not reliable, PF_EXITING could be set on another cpu without any locks/barriers just after the check, so it can't prevent from attaching the timer to the exiting task. The previous patch makes this check unneeded. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
