Subject: [PATCH 0/2] xen/gntalloc: fix oopses after running out of grant refs
Date: Tue, 2 Sep 2014 15:21:28 +0100 [thread overview]
Message-ID: <1409667690-23914-1-git-send-email-david.vrabel@citrix.com> (raw)
These two patches fix oopses that happen if a grant failed because
there are no free grant references.
This would not happen on a typical system with the default options as
the gntalloc device limits the number of pages that may be granted and
this check fails first, but could be triggered on VM with many PV
devices or if the limit is increase.
