Subject: [PATCH v4 22/32] cxlflash: Remove unnecessary scsi_block_requests
Date: Fri, 25 Sep 2015 18:17:49 -0500	[thread overview]
Message-ID: <1443223069-9770-1-git-send-email-mrochs@linux.vnet.ibm.com> (raw)
In-Reply-To: <1443222593-8828-1-git-send-email-mrochs@linux.vnet.ibm.com>

The host reset handler is called with I/O already blocked, thus
there is no need to explicitly block and unblock I/O in the handler.
