Davidlohr Bueso fce45cd411 locking/rwsem: Check for operations on an uninitialized rwsem ... Currently rwsems is the only locking primitive that lacks this debug feature. Add it under CONFIG_DEBUG_RWSEMS and do the magic checking in the locking fastpath (trylock) operation such that we cover all cases. The unlocking part is pretty straightforward.
