Name:st_and_set_bit_lock - Set a bit and return its old value, for lock*@nr: Bit to set*@addr: Address to count from* This operation is atomic and provides acquire barrier semantics if* the returned value is 0.* It can be used to implement bit locks.
Proto:static inline bool test_and_set_bit_lock(long nr, volatile unsigned long *addr)
Type:bool
