Subject: [PATCH 0 of 9] x86/mm: Fixes to sharing, paging and p2m
Date: Wed, 01 Feb 2012 14:51:52 -0500 [thread overview]
Message-ID: <patchbomb.1328125912@xdev.gridcentric.ca> (raw)
This patch series aggregates a number of fixes to different areas of mm:
Sharing:
- Make sharing play nice with balloon
- Make physmap manipulations deall correctly with shared pages
- Make sharing debug calls use locked accessors and return useful information
Paging:
- Eliminate a needless state in the paging state machine
- Fix stats/accounting
- Fix page type check when nominating or evicting a page
P2M:
This changes clear hurdles in advance of a fully-synchronized p2m
- Eliminate possibility of deadlock in nested lookups
- Reorder some locks taken by the sharing subsystem
