Hi Peter,
I bumped into an odd futextest regression, and finally bisected it to $subject. I haven't poked at it yet, chasing down and confirming the little bugger munched the day.
#!/bin/sh
cd /home/git/futextest/functional trap "killall -KILL -q cpuhog;exit;" INT
for i in `seq 0 7`; do taskset -c $i cpuhog& done sleep 1 for i in `seq 1000` do echo iteration $i ./futex_requeue_pi -c -b -o -t 500000 done killall cpuhog
Without the cpuhogs, it won't hang.
-Mike
