H A Dtarget_core_internal.h2ed22c9c Wed Jan 08 12:19:31 CST 2014 Nicholas Bellinger <nab@linux-iscsi.org> target/configfs: Expose protection device attributes

This patch adds support for exposing DIF protection device
attributes via configfs. This includes:

pi_prot_type: Protection Type (0, 1, 3 currently support)
pi_prot_format: Protection Format Operation (FILEIO only)

Within se_dev_set_pi_prot_type() it also adds the se_subsystem_api
device callbacks to setup per device protection information.

v2 changes:
- Drop pi_guard_type + pi_prot_version related code (MKP)
- Add pi_prot_format logic (Sagi)
- Add ->free_prot callback in target_free_device
- Add hw_pi_prot_type read-only attribute
