Hi = SJ,

Thank you for = the suggestion.  I will study MTHP_STAT_NR_ANON and = nr_anon
further, and document what I find.  We can continue = discussing it by email,
and I will be happy to review any follow-up = or updated patches.

I'm curious if you = and general reviewers need or prefer to directly be Cc-ed.
I was = naively thinking people can search and review DAMON patches = by
subscribing to the mailing list or using the archives via = lore.kernel.org like
tools.

I subscribe to many = mailing lists, including linux-mm and DAMON, and I also
follow = patches through lore.  Direct Cc is not required, but I appreciate = it
for DAMON-related patches.  Because I care deeply about = DAMON, directly Cc-ed
messages are filtered into my important = mailbox, so I can archive and review
them = quickly.

Thank you so much for your interest in = DAMON, Lian.  But, the problem is that
my memory is so bad. :'(

I am maintaing mm patches review status = dashboard for people who want to find
patches that waiting for their review. =  It also provides the review status for
each sub-mm components [2] including DAMON = [3].  Maybe finding patches that
waiting for your review from the dashboard = is also a way for you?

If having the mail directly in your = important mailbox is what you need, I
believe adding mails filtering rule for = DAMON patches wouldn't be that
difficult.  If you use hkml, it could = also help you monitoring [4] those.

Yet another systematic and long term = solution that I could suggest is keep
reviewing and posting DAMON patches one by = one, build more tracked records and
trusts, eventually adding your name as = DAMON reviewer or maintainer on the
MAINTAINERS file.  All patches sent = with get_maintainers.pl will automatically
Cc you.  It would take time and = require patience, though, of course.
Thank you for your detailed = feedback.


I am very happy to contribute to DAMON, and I look forward = to continuing our
discussions and reviews by = email.

I really appreciate your interest and = contributions to DAMON.  I hope it to be
continued long term!
