Yes, highly appreciated indeed. I'm on opensuse 10.0 too, and after
realizing that rlimits are not working OTOB I always find myself patching
the original kernel-source with realtime-lsm, over and over again.

AFAICT the question really is _why_ the rlimits is not working on
opensuse10 kernel-2.6.13-15.7 ? pam-0.80 looks to be rtprio ready ...

Anyone else?
