NO, they are here: > > http://redhat.com/~mingo/realtime-preempt/ > Lots of people seem to be confused on this. I even read an lwn.net article that didn't seem to grok the distinction. The realtime-preempt patches make the Linux kernel usable for soft and hard realtime applications. The realtime LSM just enables the administrator to let selected non-root users use these capabilities. The only relationship between the patches is that using the realtime LSM is rather pointless without the realtime preempt patch, because if the realtime performance of the Linux kernel isn't good enough, there's no point in being able to let non root users use it.
