nbd: update size when connected
commit c3f7c9397609705ef848cc98a5fb429b3e90c3c4 upstream. I messed up changing the size of an NBD device while it was connected by not actually updating the device or doing the uevent. Fix this by updating everything if we're connected and we change the size. cc: stable@vger.kernel.org Fixes: 639812a ("nbd: don't set the device size until we're connected") Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
