mainline inclusion from mainline-v6.7-rc1 commit d41592435cde9a658a1bd3b3fdfeb8db7b330d78 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8T2RT
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
resctrl associates rftype 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 the prefix to RFTYPE_ for all these flags to be consistent.
