Subject: Re: [PATCH v2 00/16] Address some perf memory/data size issues
Date: Mon, 29 May 2023 21:57:33 -0700 [thread overview]
Message-ID: <ZHWCPXKo2fFJmtlT@tassilo> (raw)
In-Reply-To: <20230526183401.2326121-1-irogers@google.com>
FWIW I think the whole patchkit could be replaced with a one liner
that disables THP for the BSS segment. I suspect that would be roughly
equivalent for memory consumption because 4K pages that are never
touched would never be allocated.
