There's no sense in comparing the realtime lsm with a -realtime-preemption 
kernel patch. The realtime lsm is something completely different from the -rt 
kernel patch. The former allows non root users to have certain privileges 
that otherwise only root has [running processes SCHED_FIFO mainly]... The 
latter is a patch for the kernel that makes linux in effect a hard rt system.

It makes more sense to comapre

a] realtime lsm vs. rtlimits in libPAM

b] a vanilla kernel vs a -rt kernel
