From: Linus Torvalds Date: Mon, 12 Dec 2005 03:46:02 +0000 (-0800) Subject: Allow arbitrary shared PFNMAP's X-Git-Tag: v2.6.15-rc6~148 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fb155c1619f056ae9765eed272cd6aba6e1a7399;p=pandora-kernel.git Allow arbitrary shared PFNMAP's A shared mapping doesn't cause COW-pages, so we don't need to worry about the whole vm_pgoff logic to decide if a PFN-remapped page has gone through COW or not. This makes it possible to entirely avoid the special "partial remapping" logic for the common case. Signed-off-by: Linus Torvalds --- Reading git-diff-tree failed
