Hi all,

After merging the tip tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

kernel/locking/mutex-debug.c: In function 'debug_mutex_lock_common':
kernel/locking/mutex-debug.c:32:42: error: dereferencing pointer to incomplete type 'struct mutex_waiter'
memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter));

Caused by commit

5f35d5a66b3e ("locking/mutex: Make __mutex_owner static to mutex.c")

I have reverted that commit for today.

BTW, there is another reference to mutex_waiter in sched.h!
