Subject: [PATCH v4 1/3] scsi: devinfo: add new flag BLIST_MEDIA_CHANGE
Date: Mon, 28 Jun 2021 15:34:10 +0200 [thread overview]
Message-ID: <20210628133412.1172068-2-martin.kepplinger@puri.sm> (raw)
In-Reply-To: <20210628133412.1172068-1-martin.kepplinger@puri.sm>
add a new flag for devices that issue MEDIA CHANGE unit attentions
when actually no medium changed. Drivers can then act accordingly in
case they need to work around it, i.e. in resume().
