Subject: [RFC PATCH 06/10] Add command-line processing for free page filtering looking up mem_map array
Date: Fri, 29 Jun 2012 02:38:44 +0900	[thread overview]
Message-ID: <20120628173844.19702.58432.stgit@fedora-machine> (raw)
In-Reply-To: <20120628173757.19702.75678.stgit@fedora-machine>

I choose dump level 32 for free page filtering looking up mem_map
array. But I don't mean this is the final version now, I mean
experimental use for RFC, only. I prefer the setting that this logic
looking up mem_map array is automatically used if dump level 16 and
--cyclic option are specified at the same time.
