From e87b03f5830ecd8ca21836d3ee48c74f8d58fa31 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 20 Oct 2020 09:33:45 +0100 Subject: afs: Prepare for use of THPs As a prelude to supporting transparent huge pages, use thp_size() and similar rather than PAGE_SIZE/SHIFT. Further, try and frame everything in terms of file positions and lengths rather than page indices and numbers of pages.
