Subject: [PATCH 07/13] aacraid: move scsi_(block,unblock)_requests out of _aac_reset_adapter()
Date: Wed,  4 Dec 2019 15:59:12 +0100
Message-ID: <20191204145918.143134-8-hare@suse.de> (raw)
In-Reply-To: <20191204145918.143134-1-hare@suse.de>

_aac_reset_adapter() only has one caller, and that one already calls
scsi_block_requests(). So move the calls out of _aac_reset_adapter()
to avoid calling scsi_block_requests() twice.
