Subject: [PATCH v13 137/137] mm/readahead: Add multi-page folio readahead
Date: Mon, 12 Jul 2021 04:07:01 +0100 [thread overview]
Message-ID: <20210712030701.4000097-138-willy@infradead.org> (raw)
In-Reply-To: <20210712030701.4000097-1-willy@infradead.org>
If the filesystem supports multi-page folios, allocate larger pages in
the readahead code when it seems worth doing. The heuristic for choosing
larger page sizes will surely need some tuning, but this aggressive
ramp-up has been good for testing.
