I have 2 more comments about the code.
1) There are a couple of places where you only use 0x3 in mutex.c. They
should be replaced by the symbolic name instead.
2) We should make __mutex_lock_slowpath() a noinline function just like
__mutex_lock_killable_slowpath() or __mutex_lock_interruptible_slowpath().
Cheers,
Longman
