Doing the same thing on 2.6.26-rc5-mm3, msgctl08 also runs to completion, in 20.9 seconds. So
- it got slower
That is because it scales itself to the number of available msg queues. So with Nadia's patch there are more and it runs slower.

In fact it seems to start one process per message queue, so perhaps it's just running out of processes or something. Ok it should not segfault.
BTW a great way to debug slab corruptions with LTP faster is to run with a slab thrasher stress module like http://firstfloor.org/~andi/crasher-26.diff

any reason why only suse has this, but not mainline ?
i came across that module in suse kernel just some days ago and asked novell ( https://bugzilla.novell.com/show_bug.cgi?id=396132 ) , but they dont have any objections. chris mason didnt reply on direct request....
so, if it`s useful, who is reponsible for pushing it upstream ?

Nobody is. That is why it isn't. Feel free to do the work.
It would need some cleanup before submission. e.g. the ooops/panic etc. options are fairly useless and should be removed and there needs to be more documentation.
