Subject: [PATCH 5/5] fs/block_dev: replace GENHD_FL_UP with GENHD_FL_DISK_ADDED
Date: Tue, 20 Jul 2021 11:20:48 -0700	[thread overview]
Message-ID: <20210720182048.1906526-6-mcgrof@kernel.org> (raw)
In-Reply-To: <20210720182048.1906526-1-mcgrof@kernel.org>

The GENHD_FL_DISK_ADDED flag is what we really want, as the
flag GENHD_FL_UP could be set on a semi-initialized device.
