tcm: make pi data verification configurable
Currently ramdisk and fileio always perform PI verification before and after backend IO. This approach is not very flexible. Because some one may want to postpone this work to other layers in IO stack. For example if we want to test blk_integrity_profile testcase: https://github.com/dmonakhov/xfstests/commit/dee408c868861d6b6871dbb3381facee7effdbe4 Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
