[PATCH 0 of 2] Paging support updates for XCP dom0
This is a cherry pick of two patches that add support for guest paged out
frames in the XCP 2.6.32 dom0 patch queue.
First patch propagates the ENOENT returned by the hypervisor in the case
of a paged out page, all the way up the call chain to the MMAPBATCH_V2
ioctl. The ioctl is mainly used to harvest those return values and retry.
The second patch adds retry loops to all backend grant

xenpaging fixes for kernel and hypervisor
Patrick,
there following patches fix xenpaging for me.
Granttable handling is incomplete. If a page is gone, a GNTST_eagain
should be returned to the caller to inidcate the hypercall has to be
retried after a while, until the page is available again.
Please review.

[PATCH 0/2] dm-ioband: I/O bandwidth controller v1.0.0: Introduction
Hi everyone,
This is dm-ioband version 1.0.0 release.
Dm-ioband is an I/O bandwidth controller implemented as a device-mapper

- Changes from 0.0.4 (24th April):
- Performance tuning
- A new bandwidth control policy is added. This policy controls
