Thank you for bringing this to our attention.

I am ok with this maintainer setup. Considering the different status roles and values
I think it best to keep these as separate entries in MAINTAINERS.

Even so, I would appreciate being aware how MPAM uses resctrl fs. Being a reviewer
(not maintainer) of the "MPAM DRIVER" should ensure that I am cc'd on future patches,
similar to the roles James and Dave (Martin) have in resctrl fs MAINTAINERS entry. I
understand this is a major addition so I can surely also just do what other folks
do when interested in following the work by using, for example, lei.
