Well, the fs this thing uses is called "resctrl".
Documentation/x86/resctrl_ui.txt:1075:the resctrl will still mount but cannot create CTRL_MON directories.
Documentation/x86/resctrl_ui.txt:1082:# mount -t resctrl resctrl /sys/fs/resctrl
Documentation/x86/resctrl_ui.txt:1083:# cd /sys/fs/resctrl
Are you saying that the fs should be renamed now too?

How are those *abbreviations* better? "hw_bw" is especially cryptic and
the others are no better.
"resctrl" to mean "resource control" is much better IMO. And it is
different from the "other" resource controlling the kernel does because
it is under arch/x86/kernel/cpu/ which tells you it is a *CPU* resource
control.
And also matches the user-visible "resctrl" filesystem.
But I don't have the energy to bikeshed this morning so whatever, as
long as it is short...
