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) Cc: Martin K.
