From 395ccb2531021974d309f26e5fb08a8240ac5f84 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Wed, 2 Apr 2014 14:34:11 -0700 Subject: target/sbc: Add sbc_dif_read_strip software emulation Split up __sbc_dif_verify_read() so that VERIFY READ emulation can perform target-core specific READ_STRIP, seperate from the existing FILEIO/RAMDISK backend emulation code. Also add sbc_dif_read_strip() in order to determine number of sectors using cmd->prot_length, and skip the extra sbc_dif_copy_prot(). Reviewed-by: Sagi Grimberg Cc: Martin K.
