Revision 10f02d1c59e55f529140dda3a92f0099d748451c authored by Samuel Thibault on 21 May 2005, 15:50:15 UTC, committed by Linus Torvalds on 21 May 2005, 17:46:48 UTC
In _spin_unlock_bh(lock): do { \ _raw_spin_unlock(lock); \ preempt_enable(); \ local_bh_enable(); \ __release(lock); \ } while (0) there is no reason for using preempt_enable() instead of a simple preempt_enable_no_resched() Since we know bottom halves are disabled, preempt_schedule() will always return at once (preempt_count!=0), and hence preempt_check_resched() is useless here... This fixes it by using "preempt_enable_no_resched()" instead of the "preempt_enable()", and thus avoids the useless preempt_check_resched() just before re-enabling bottom halves.
