Subject: [PATCH 0 of 2] RFC Switch mem event ABI from domctl to memops
Date: Thu, 26 Jan 2012 08:08:43 -0500 [thread overview]
Message-ID: <patchbomb.1327583323@xdev.gridcentric.ca> (raw)
Swith mem event per page operations from domctl to XENMEM_* interface. Improve
scalabilty.
Looking for further feedback on the proposed ABI change.
This code has been tested to work generally well, save for a few blue screens.
It might be that removing the global domctl lock uncovers hidden races.
