From: Frederic Weisbecker Date: Thu, 16 Jul 2009 13:44:29 +0000 (+0200) Subject: sched: Pull up the might_sleep() check into cond_resched() X-Git-Tag: v2.6.32-rc1~719^2~44 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=613afbf83298efaead05ebcac23d2285609d7160;p=pandora-kernel.git sched: Pull up the might_sleep() check into cond_resched() might_sleep() is called late-ish in cond_resched(), after the need_resched()/preempt enabled/system running tests are checked. It's better to check the sleeps while atomic earlier and not depend on some environment datas that reduce the chances to detect a problem. Also define cond_resched_*() helpers as macros, so that the FILE/LINE reported in the sleeping while atomic warning displays the real origin and not sched.h Changes in v2: - Call __might_sleep() directly instead of might_sleep() which may call cond_resched() - Turn cond_resched() into a macro so that the file:line couple reported refers to the caller of cond_resched() and not __cond_resched() itself. Changes in v3: - Also propagate this __might_sleep() pull up to cond_resched_lock() and cond_resched_softirq() Signed-off-by: Frederic Weisbecker Signed-off-by: Peter Zijlstra LKML-Reference: <1247725694-6082-6-git-send-email-fweisbec@gmail.com> Signed-off-by: Ingo Molnar --- Reading git-diff-tree failed
