Subject: xen_biovec_phys_mergeable not exported

In my NVMe driver, I call BIOVEC_PHYS_MERGEABLE().  If CONFIG_XEN
is defined, it references xen_biovec_phys_mergeable() which is not
EXPORT_SYMBOL.  I think BIOVEC_PHYS_MERGABLE is a perfectly kosher thing
to be calling from a module that implements a bio-based block driver,
so I think the right thing to do is to add an EXPORT_SYMBOL(_GPL?) to
the Xen code when I submit the driver.

Does anyone have a different opinion on this?
