From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nick Piggin Message-Id: <20061009140354.13840.71273.sendpatchset@linux.site> Subject: [rfc] 2.6.19-rc1-git5: consolidation of file backed fault handlers Date: Mon, 9 Oct 2006 18:12:06 +0200 (CEST) Sender: owner-linux-mm@kvack.org Return-Path: To: Hugh Dickins , Linux Memory Management Cc: Andrew Morton , Jes Sorensen , Benjamin Herrenschmidt , Linux Kernel , Nick Piggin , Ingo Molnar List-ID: OK, I've cleaned up and further improved this patchset, removed duplication while retaining legacy nopage handling, restored page_mkwrite to the ->fault path (due to lack of users upstream to attempt a conversion), converted the rest of the filesystems to use ->fault, restored MAP_POPULATE and population of remap_file_pages pages, replaced nopfn completely, and removed NOPAGE_REFAULT because that can be done easily with ->fault. In the process: - GFS2, OCFS2 theoretically get nonlinear mapping support - Nonlinear mappings gain page_mkwrite and dirty page throttling support - Nonlinear mappings gain the fault vs truncate race fix introduced for linear All pretty much for free. This is lightly compile tested only, unlike the last set, mainly because it is presently just an RFC regarding the direction I'm going (and it's bedtime).
