Rephrased the whole changelog.

"fs/resctrl: Pass the full rdtgroup structure instead of individual RMID
and CLOSID

The functions resctrl_arch_reset_rmid() and resctrl_arch_rmid_read()
require several parameters, including RMID and CLOSID. Currently, RMID and
CLOSID are passed individually, even though they are available within the
rdtgroup structure.

Refactor the code to pass a pointer to struct rdtgroup instead of
individual members in preparation for this requirement.

Additionally, when "mbm_event" counter assignment mode is enabled, a
counter ID is required to read the event. The counter ID is obtained
through mbm_cntr_get(), which expects a struct rdtgroup pointer."


Thanks
Babu
