I am refering to this bug:

A thread led to a patch from Paulo:
http://kerneltrap.org/mailarchive/1/message/59454/flat
This patch has been included in the kernel 2.6.12.
1. How can I easily check if the patch is planned for include in the 2.4?
2. I downloaded the full 2.4.31 source code. The patch appears not to be
included. Where/Who should I signal that?
And what about the side effects:
This however will produce pathological cases, like having a idle system
being requested 1 ms timeouts will give systematically 2 ms timeouts,
whereas currently it simply gives a few usecs less than 1 ms.
I don't see why an idle system would align such request in this way any more
than a busy one. In both cases the range would be ~0 to 1ms (which is what the
standard says it should be) with an average of .5ms. Any other result is caused
by syncing, in some way with the tick clock.
(20ms rather than 10ms)
Linus, Andrew, do you consider this critical enough to be merged to
the v2.4 tree?
No. I'd expect this would hurt more people than it would benefit.
Still, it is the "correct" thing to do (standard wise, etc...).
It is rather amazing that this has been in the system this long. Should have
been fixed long ago...
