For non null timeouts, the __futex_clocklock_wait64 creates an a relative timeout by subtracting the current time from the input argument. The same behavior can be obtained with FUTEX_WAIT_BITSET without the need to calculate the relative timeout. Besides consolidate the code it also avoid the possible relative timeout issues [1]. The __futex_abstimed_wait64 needs also to return EINVAL syscall errors. Checked on x86_64-linux-gnu and i686-linux-gnu.
