Subject: [PATCH 3/6] scsi_debug: fix duplicate dif_errors increment
Date: Mon,  6 Jan 2014 08:33:09 +0900	[thread overview]
Message-ID: <1388964792-3546-4-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1388964792-3546-1-git-send-email-akinobu.mita@gmail.com>

It is unnecessary to increase dif_errors in dif_verify(), because the
caller will increment it when dif_verify() detects failure.

This bug was introduced by commit beb40ea42bd6 ("[SCSI] scsi_debug:
reduce duplication between prot_verify_read and prot_verify_write")
