Date: Wed, 4 Aug 2010 08:15:02 -0400 From: Ed Tomlinson <edt@....ca> To: Andrea Arcangeli <aarcange@...hat.com> Cc: linux-kernel@...r.kernel.org Subject: Re: Transparent Hugepage Support #29 Andrea, I have been tracking & testing this for a while. It looks very much like Linus wants to merge (or a big chunk of it): git://git.kernel.org/pub/scm/linux/kernel/git/npiggin/linux-npiggin.git vfs-scale-working When I pull an aa-29 on top of this there is one conflict in vmscan.c that git cannot resolve. It would be really nice to have a version of the THS patchs that can be tested with the vfs scaling tree.
