[Xen-devel] [RFC] [PATCH] xen, vtd: Check ownership of a domain context using internal structures

Keir, Jan, et al:

Can you take a look at this patch to see if you think this is the
right way to solve this problem?

This particular patch is still being tested by the partner who saw the
problem; but a less safe change -- just returning "OK" if the pci
device didn't exist -- did solve the problem.  It seemed like this
check was probably there for a reason, so I wanted to keep it in
place.  (Although the c/s in which this check was introduced,
18906:2941b1a9, only mentioned locking changes, not introduction of
new checks.)
