Log message:
__thrsleep(2): fix absolute timeout check
An absolute timeout T elapses when the clock has reached time T, i.e.
when T is less than or equal to the clock's current time.
But the current code thinks T elapses only when the clock is strictly
greater than T.
For example, if my absolute timeout is 1.00000000, the current code will
not return EWOULDBLOCK until the clock reaches 1.00000001. This is wrong:
my absolute timeout elapses a nanosecond prior to that point.
So the timespeccmp(3) here should be
timespeccmp(tsp, &now, <=)
and not
timespeccmp(tsp, &now, <)
as it is currently.
