[PATCH] MAINTAINERS: mark MGLRU as maintained

Posted by Axel Rasmussen 1 month, 2 weeks ago

The three folks being added here are actively working on MGLRU within
Google, so we can review patches for this feature and plan to contribute
some improvements / extensions to it on an ongoing basis.

With three of us we may have some hope filling Yu Zhao's shoes, since he
has moved on to other projects these days.

Why not just add yourselves (and the missing files) to the existing
reclaim section? Eventually we want a single reclaim solution, so why
not start with single reviewer section?

Sure, I can see the argument for that.

I suppose the case against would be, perhaps the folks already listed
in the RECLAIM section don't want to additionally get e-mail for the
extra files listed in this patch? (Perhaps mostly the MGLRU
documentation, the rest of them aren't necessarily MGLRU specific.)

I don't have a strong preference either way, I think mostly I'd be
interested to know Andrew's or the other reviewers' preference. Note
Lorenzo suggested a separate MGLRU section here:

I would not be too worried about folks getting emails for MGLRU. Anyways
whatever Andrew decides is fine with me.

We all like lots of emails, don't we?

I don't know, the main thing is to get it in there - we can fine-tune
things later if desired.
