Man page http://man7.org/linux/man-pages/man2/futex.2.html
states for FUTEX_CMP_REQUEUE
Typical values to specify for val are 0 or 1.
How is a value of 0 useful?
(Specifying
INT_MAX is not useful, because it would make the
FUTEX_CMP_REQUEUE operation equivalent to FUTEX_WAKE.)
This is incorrect because FUTEX_WAKE doesn't have the expected (val3)
parameter.
Same for the remark that follows this statement after "The
limit value specified via val2 is typically either 1 or
INT_MAX.":
(Specifying the argument as 0 is not useful, because
it would make the FUTEX_CMP_REQUEUE operation equivalent
to FUTEX_WAIT.)
