Subject: [PATCH 5/5] nbd: call nbd_bdev_reset instead of bd_set_size on disconnect
Date: Wed, 16 May 2018 14:36:05 -0400	[thread overview]
Message-ID: <20180516183605.16159-5-josef@toxicpanda.com> (raw)
In-Reply-To: <20180516183605.16159-1-josef@toxicpanda.com>

From: Josef Bacik <jbacik@fb.com>

We need to make sure we don't just set the size of the bdev to 0 while
it's being used by a file system.  We have the appropriate check in
nbd_bdev_reset, simply use that helper instead.
