From ddd0bc756983dc4d19000a4fe021b4c7f9d59aab Mon Sep 17 00:00:00 2001 From: Max Gurtovoy Date: Mon, 30 Jul 2018 00:15:31 +0300 Subject: block: move ref_tag calculation func to the block layer Currently this function is implemented in the scsi layer, but it's actual place should be the block layer since T10-PI is a general data integrity feature that is used in the nvme protocol as well.
