Subject: [PATCH 04/10] nvdimm/btt: do not call del_gendisk() if not needed
Date: Fri, 27 Aug 2021 12:18:03 -0700 [thread overview]
Message-ID: <20210827191809.3118103-5-mcgrof@kernel.org> (raw)
In-Reply-To: <20210827191809.3118103-1-mcgrof@kernel.org>
We know we don't need del_gendisk() if we haven't added
the disk, so just skip it. This should fix a bug on older
kernels, as del_gendisk() became able to deal with
disks not added only recently, after the patch titled
"block: add flag for add_disk() completion notation".
