Hi,

commit 46de1a6ec3dbb0db203baa6c46cb64ba9b000ea2 changed the
parameters of btrfs_read_and_process_send_stream().  This breaks
snapper compilation so I wonder whether we can include version
defines usable for the C preprocessor.  Surely it won't help in
this case anymore but might in the future.

Please find my proposal attached.

Regards,
  Arvin
