Please read discussions surrounding #3 and #30 of v1. Note in particular suggestion in [1] to keep RF flags internal to FS code. If MPAM chooses to submit new versions without completing discussions then I have no problem letting ABMC proceed to build on what is resctrl at this time and adding this to the pile of things MPAM needs to address during fs/arch split.
