[PATCH v5 34/34] MAINTAINERS: new entry for MPAM Driver
Posted by Ben Horgan 2 weeks ago 
Create a maintainer entry for the new MPAM Driver. Add myself and
James Morse as maintainers. James created the driver and I have
taken up the later versions of his series.

Maybe to squeeze those two lines into one if another respin is needed.
LGTM in either way.

Btw, I think the only one I didn't tag was 33 and that's just
because I'm too lazy to check all the test cases :)

Greg, are you ok with the above maintainers entry? Happy to queue
patches for this via the arm64 tree (or at least the initial drop).

Reinette, Tony, I now realised you haven't been cc'ed on this series:

https://lore.kernel.org/r/20251117170014.4113754-1-ben.horgan@arm.com

While it doesn't touch fs/resctrl/, it's going to be a user of that API.
Are you ok with this maintainer setup? I wouldn't mind at all if you
want to be a co-maintainers or reviewers of drivers/resctrl/* (e.g.
adding this under the RDT entry) but I guess you would not be looking
forward to more email traffic.

Thanks.

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.
