Subject: [PATCH RESEND 0/3] Memory reclaim documentation fixes
Date: Mon, 10 Nov 2025 20:36:32 +0100 [thread overview]
Message-ID: <20251110193638.623208-1-mkoutny@suse.com> (raw)
I think the reclaim target is a concept that is not just an
implementation detail and hence it should be documented how it applies
to protection configuration (the first patch). Second patch is a "best
practice" bit of information, it may be squashed with the first one. The
last patch just makes docs indefinite until the idea is implemented.
Originally sent in [1], this is rebased and resent since I still think
it'd be good to have the concept somewhere documented. (E.g. for the
guys who are implementing protection for the dmem controller [2] to
arrive at similar behavior.)
