Hi,
this might be old news already, but just in case...:

The 2.6.6-mm1 tree includes, among many other things, patches which add
two new /proc/sys variables. They are:
/proc/sys/vm/hugetlb_shm_group
If this value is non-zero, it is interpreted as a group ID which
gives access to the the "huge pages" feature of the 2.6 VM.
/proc/sys/vm/mlock_group
This variable behaves similarly, but it controls access to the
mlock() system call (which locks memory into physical RAM) instead.

And continues with comments from Andrew:

The problem, it seems, is that there are no better solutions on the
horizon. Says Andrew Morton:
""Capabilities are broken and don't work. Nobody has a clue how to provide
the required services with SELinux and nobody has any code and we need the
feature *now* before vendors go shipping even more ghastly stuff. ""

This suggests that there is a good chance that realtime-lsm could be
accepted to the mainline kernel tree, if submitted!
