__mutex_lock_commonLock a mutex (possibly interruptible), slowpath:
__down_commonBecause this function is inlined, the 'state' parameter will be* constant, and thus optimised away by the compiler. Likewise the* 'timeout' parameter for the cases without timeouts.
rwsem_down_read_slowpathWait for the read lock to be granted
rwsem_down_write_slowpathWait until we successfully acquire the write lock
