Subject: [PATCH -next v3 1/2] nbd: Fix incorrect error handle when first_minor big than '0xff' in nbd_dev_add
Date: Mon, 1 Nov 2021 14:29:55 +0800 [thread overview]
Message-ID: <20211101062956.791573-2-yebin10@huawei.com> (raw)
In-Reply-To: <20211101062956.791573-1-yebin10@huawei.com>
If first_minor big than '0xff' goto out_free_idr label, this will miss
cleanup disk.
