See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org So what is the result here? Not having folios (with that or another name) is really going to set back making progress on sane support for huge pages. Both in the pagecache but also for other places like direct I/O.
