Hi Babu,

Files unique to monitoring groups have the RFTYPE_MON flag. When a new
monitoring group is created the resctrl files with flags RFTYPE_BASE
(files common to all resource groups) and RFTYPE_MON (files unique to
monitoring groups) are created to support interacting with the new
monitoring group.

A resource group can support both monitoring and control, also termed
a CTRL_MON resource group. CTRL_MON groups should get both monitoring
and control resctrl files but that is not the case. Only the
RFTYPE_BASE and RFTYPE_CTRL files are created for CTRL_MON groups.
This is not a problem because there are no monitoring specific files
with the RFTYPE_MON flag associated with resource groups.

A later patch introduces the first monitoring specific (RFTYPE_MON)
file for resource groups. Ensure that files with the RFTYPE_MON
flag are created for CTRL_MON groups.

Thank you.

I believe this series is ready for inclusion. There is a conflict between
this series and Maciej's non-contiguous work [1] that is also ready for
inclusion. We could wait for outcome of next level review to determine
who will need to rebase. It may help to provide a snippet of the conflict
resolution in anticipation of Maciej's series being merged first (I will
propose the same to Maciej for the scenario of this work merged first).

I had a minor comment on Maciej's patch.

I will respond to his patch 3 with the conflict resolution.

Thanks
