uio: Export definition of struct uio_device
In order to prevent a O(n) search of the filesystem to link up its uio node with its target configuration, TCMU needs to know the minor number that UIO assigned. Expose the definition of this struct so TCMU can access this field. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
