Modified Files:
        src/sys/arch/xen/xen [netbsd-3-0]: xbdback.c

Log Message:
Pull up following revision(s) (requested by bouyer in ticket #1106):
        sys/arch/xen/xen/xbdback.c: revision 1.16 via patch
When disconnecting a device, we have to wait for pending I/O before releasing
the ressources (this can lead to a dom0 kernel crash when destroying a domain
with active I/O going). For this, add a refcount to struct xbdback_instance,
and defer CMSG_BLKIF_BE_DISCONNECT reply until refcount is back to 0 (which
means all queued buffers have completed).
Based on patch sent by Jed Davis on port-xen.
