It was posted more than once. I posted 6 patches (1/4,2/4,3/4,4/4,5/4,6/4), they should be all applied to mainline, they're self contained. They add the userspace ratings too. Those patches fixes a longstanding PF_MEMDIE race too and they optimize used_math as well. I'm running with all 6 patches applied with an uptime of 6 days on SMP and no problems at all. They're all 6 patches applied to the kotd too (plus the other bits posted on l-k as well for the write throttling, just one bit is still missing but I'll add it soon): ftp://ftp.suse.com/pub/projects/kernel/kotd/i386/HEAD
