Is kmem_cache_free safe to call while holding a spinlock (can
kmem_cache_free ever block or recurse into a file system)?

I see it trying to grab just another spinlock which is probably fine
(but was worried whether any of the worker functions called a sem) ...
my assumption is that it would be safe, but the man page doesn't
mention when it can be used safely.
