At a slight footprint cost (24 vs 32 bytes), mutexes are more optimal than semaphores; it's also a nicer interface for mutual exclusion, which is why they are encouraged over binary semaphores, when possible. There is also lockdep support. For both f_sem and b_sem, their semantics imply traditional lock ownership; that is, the lock owner is the same for both lock/unlock operations and not under irq contexts (ie for trylock/unlock scenarios). Therefore it is safe to convert.
