What about adding a wrapper type and leaving the name as is to avoid this? The type is called something like mmap_sem_struct. That means the lockdep/might_lock/prefetch/etc calls have to have the indirection inline, but that seems ok. The main value of the series seems to be paving the way for instrumentation, not making the type totally abstract.
