H A Dtarget_core_file.h0f5e2ec4 Sat Jan 18 03:32:56 CST 2014 Nicholas Bellinger <nab@linux-iscsi.org> target/file: Add DIF protection init/format support

This patch adds support for DIF protection init/format support into
the FILEIO backend.

It involves using a seperate $FILE.protection for storing PI that is
opened via fd_init_prot() using the common pi_prot_type attribute.
The actual formatting of the protection is done via fd_format_prot()
using the common pi_prot_format attribute, that will populate the
initial PI data based upon the currently configured pi_prot_type.

Based on original FILEIO code from Sagi.

v1 changes:
- Fix sparse warnings in fd_init_format_buf (Fengguang)
