8   When a device needs to advertise itself as being able
9   to send/receive integrity metadata it must use this function to
10   register the capability with the block layer.  The template is a
11   blk_integrity struct with values appropriate for the underlying
12   hardware.  If template is NULL the new profile is allocated but
13   not filled out. See Documentation/block/data-integrity.txt.
