Subject: [PATCH 08/16] btrfs: initialize sysfs devid and device link for seed device
Date: Sat, 5 Sep 2020 01:34:28 +0800 [thread overview]
Message-ID: <4168e0fed4945939eaba9848c9814970a2137d6f.1599234146.git.anand.jain@oracle.com> (raw)
In-Reply-To: <cover.1599234146.git.anand.jain@oracle.com>
We don't initialize the sysfs devid kobject and device-link yet for the
seed devices in an sprouted filesystem.
So this patch initializes the seed device devid kobject and the device
link in the sysfs.
