Hello,

This patch:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=4ee303dfeac6451b402e3d8512723d3a0f861857

looks wrong.

In PSCHED_TADD2, if delta is less than tv.tv_usec (so, less than 
USEC_PER_SEC too) then tv_res will be before tv. The
affectation (tv_res).tv_usec = __delta; is wrong. The same applies to 
PSCHED_TADD.

I think the correct fix is simply to restore the original code and 
change the 'if' in a 'while'.

So here are two patches for the two possible solutions :

o Reverting the commit and applying from_before_patch_to_correct.diff

o Applying from_tip_to_correct.diff


Thanks.
