As I mentioned in response [4] to Tony this fundamentally changes the behavior users can expect from the default resource group. In addition, this breaks the first of the "Resource monitoring rules" from Documentation/filesystems/resctrl.rst: 1) If a task is a member of a MON group, or non-default CTRL_MON group then RDT events for the task will be reported in that group. How does this fit with the ABMC work? I continue to think that I am missing parts of the discussion as it seems this new feature discussion mixed in with ABMC work.
