I would be careful with the term "rftype flags" since it is
not clear what is meant by this. Note that there are RF_*, RFTYPE_*,
as well as RFTYPE_FLAGS* flags and the reader may easily think that
you refer to the latter.

"resctrl associates flags with its files so that files can be chosen
based on the resource, whether it is info or base, and if it is control
or monitor type file. These flags use the RF_ as well as RFTYPE_ prefixes.

Change ..."

(A shortcut I used was to look up the commit that introduced the change
and borrow some text from it.)
