Subject: [PATCH 03/18] ledtrig-blkdev: Add function placeholders needed by block changes
Date: Fri, 3 Sep 2021 15:45:33 -0500 [thread overview]
Message-ID: <20210903204548.2745354-4-arequipeno@gmail.com> (raw)
In-Reply-To: <20210903204548.2745354-1-arequipeno@gmail.com>
Add ledtrig_blkdev_disk_init() and ledtrig_blkdev_disk_cleanup()
placeholders. (Implementations depend on block subsystem changes in
next commit.)
