Sets the indicated lock_bit in address. If the bit is already set, this call will block until g_bit_unlock() unsets the corresponding bit.
Attempting to lock on two different bits within the same integer is not supported and will very probably cause deadlocks.
The value of the bit that is set is (1u << bit). If bit is not between 0 and 31 then the result is undefined.
This function accesses address atomically. All other accesses to address must be atomic in order for this function to work reliably.
