Boris,
I got the tip bot message that you have applied:
c2427e70c163 ("x86/resctrl: Implement new mba_MBps throttling heuristic")
I see that you also applied:
fc747eebef73 ("x86/resctrl: Remove redundant variable in mbm_config_write_domain()")
Does that empty your resctrl queue except for the SNC series? If it does, then I'll rebase SNC patches onto TIP x86/cache.
-Tony
