From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tim Deegan Subject: [PATCH 0 of 6] [RFC] Use wait queues for paging, v2 Date: Thu, 23 Feb 2012 16:34:22 +0000 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org To: xen-devel@lists.xensource.com Cc: andres@gridcentric.ca, olaf@aepfle.de, adin@gridcentric.ca List-Id: xen-devel@lists.xenproject.org This is v2 of the patch I posted last week, after feedback from Andres. The first four patches are cleanups that should probably happen even if the main waitq patch doesn't go in. Patch 5 is the waitq patch, updated but largely following the same approach. I'm not suggesting it be applied right now because I know at least one path (get_two_gfns()) needs work before it's safe. Patch 6 is a follow-up to avoid claiming a slot unnecessarily in p2m_mem_paging_populate(); it's also a good idea even if the main waitq patch doesn't happen but would need to be backported since it only applies on top of those changes. Tim.
