[Qemu-devel] [PULL 1/3] xen: add a global indicator for grant copy being available

[Stefano Stabellini]

From: Juergen Gross <jgross@suse.com>

The Xen qdisk backend needs to test whether grant copy operations is
available in the kernel. Unfortunately this collides with using
xengnttab_set_max_grants() on some kernels as this operation has to
be the first one after opening the gnttab device.

In order to solve this problem test for the availability of grant copy
in xen_be_init() opening the gnttab device just for that purpose and
closing it again afterwards. Advertise the availability via a global
flag and use that flag in the qdisk backend.

[Qemu-devel] [PULL 2/3] xen: dont try setting max grants multiple times

[Stefano Stabellini]

From: Juergen Gross <jgross@suse.com>

Trying to call xengnttab_set_max_grants() with the same file handle
might fail on some kernels, as this operation is allowed only once.

This is a problem for the qdisk backend as blk_connect() can be
called multiple times for a domain, e.g. in case grub-xen is being
used to boot it.

So instead of letting the generic backend code open the gnttab device
do it in blk_connect() and close it again in blk_disconnect.

[Qemu-devel] [PULL 3/3] xen: Log errno rather than return value

[Stefano Stabellini]

From: Ross Lagerwall <ross.lagerwall@citrix.com>

xen_modified_memory() sets errno to communicate what went wrong so log
this rather than the return value which is not interesting.
