ERROR: "percpu_down_write" [kernel/locking/locktorture.ko] undefined! ERROR: "percpu_up_write" [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@canb.auug.org.au
