Good idea. Since these new files/directories are associated with some
resctrl internals, perhaps the reserved prefix could be "resctrl_".

Plausibly someone might be naming their CTRL_MON groups with this
prefix, I'd hope that the redundancy in full pathnames like:

/sys/fs/resctrl/resctrl_xxx

would have deterred them from such a choice.

But I'm generally bad at naming things, so other suggestions welcome
(as long as this doesn't turn into a protracted bike-shedding event :-)
