Subject: [PATCH RESEND 3/3] ublk: pass NULL to blk_mq_alloc_disk() as queuedata
Date: Tue, 7 Feb 2023 15:08:39 +0800 [thread overview]
Message-ID: <20230207070839.370817-4-ZiyangZhang@linux.alibaba.com> (raw)
In-Reply-To: <20230207070839.370817-1-ZiyangZhang@linux.alibaba.com>
queuedata is not referenced in ublk_drv and we can use driver_data
instead. Pass NULL to blk_mq_alloc_disk() as queuedata while allocating
ublk's gendisk.
