Shutemov" , Hugh Dickins , Matthew Wilcox Subject: [PATCH 0/2] Better support for THP in page cache Date: Thu, 22 Nov 2018 13:32:22 -0800 Message-Id: <20181122213224.12793-1-willy@infradead.org> X-Mailer: git-send-email 2.14.5 Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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.
