Subject: [PATCH 0/2] Better support for THP in page cache
Date: Thu, 22 Nov 2018 13:32:22 -0800 [thread overview]
Message-ID: <20181122213224.12793-1-willy@infradead.org> (raw)
This is the first step towards representing THPs more efficiently in
the page cache. The next step is to insert one head page instead of
HPAGE_PMD_NR. This passes a Trinity run, but I'm sure there's a
better test-case out there for THP.
