Hi Paul, After merging the rcu tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "sched_setscheduler_nocheck" [kernel/locking/locktorture.ko] undefined! ERROR: "percpu_down_write" [kernel/locking/locktorture.ko] undefined! ERROR: "percpu_up_write" [kernel/locking/locktorture.ko] undefined! ERROR: "percpu_down_read" [kernel/locking/locktorture.ko] undefined! ERROR: "percpu_up_read" [kernel/locking/locktorture.ko] undefined! ERROR: "__percpu_init_rwsem" [kernel/locking/locktorture.ko] undefined! Caused by commits 04be76a9b067 ("locktorture: Support rtmutex torturing") 40b2996f9b32 ("locktorture: Add torture tests for percpu_rwsem") and maybe more. I have used the rcu tree from next-20150831 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
