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.
Olaf

Hello,
http://pasik.reaktio.net/xen/patches/xen-pvscsi-drivers-linux-2.6.32.27-pvops-v01.diff

pvops xen/stable-2.6.32.x branch.
At the moment it''s *only* compile-tested with the latest xen/stable-2.6.32.x

[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

set_phys_to_machine not exported?
I''m trying to compile pvscsi out-of-tree, and I''m getting an error that set_phys_to_machine is not defined when I try to load the module (with the warning to that effect at compile time too). This used to work fine in pvops.
It seems that netfront uses that symbol in a module so I''m confused as to why pvscsi can''t... any suggestions? Is it one of the virtues of
