Subject: [PATCH 00 of 18] Memory sharing overhaul
Date: Thu, 08 Dec 2011 02:47:15 -0500 [thread overview]
Message-ID: <patchbomb.1323330435@xdev.gridcentric.ca> (raw)
This patch series proposes an overhaul of the memory sharing code.
Aside from bug fixes and cleanups, the main features are:
- Polling of stats via libxc, libxl and console
- Removal of global sharing hashtable and global sharing lock
(if audit disabled)
- Turned sharing audits into a domctl
- New domctl to populate vacant physmap entries with shared
pages.
As a result, the domctl interface to sharing changes. The only in-tree
consumer of this interface is updated in the current series. It is
important that if any out-of-tree consumer exists, that they state
their opinion on this interface change.
Patches 5 to 8, 10, 11, 15 and 18 are tools patches.
