Subject: [PATCH 05/11] pmcraid: select first available device for target reset
Date: Mon,  2 May 2022 23:59:44 +0200	[thread overview]
Message-ID: <20220502215953.5463-10-hare@suse.de> (raw)
In-Reply-To: <20220502215953.5463-1-hare@suse.de>

As we're moving away from using a scsi command as argument for
eh_XX callbacks we should be selecting the first available device
for sending a target reset to.
