Subject: [PATCH v2 23/30] cxlflash: Remove unnecessary scsi_block_requests
Date: Wed, 16 Sep 2015 11:59:48 -0500	[thread overview]
Message-ID: <1442422788-41882-1-git-send-email-mrochs@linux.vnet.ibm.com> (raw)

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.
