Hi Lai,

Looks about ready to me, only a couple of more nitpics from me.


Fixed, thanks.

Looks good to me. How did the futextest runs go?


It's OK, the result are almost the same.

kernel version: 2.6.37-rc6-tip
Intel(R) Pentium(R) D CPU 2.80GHz
MemTotal: 961208 kB


This is futex_wait.c I presume? Delta looks to be in the realm of statistical noise to me. I'll ack the two patches.
