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 Signed-off-by: Jens Axboe --- diff --git a/drivers/block/nbd.c b/drivers/block/nbd.c index 9710a0c338b0..b709abf3cb79 100644 --- a/drivers/block/nbd.c +++ b/drivers/block/nbd.c @@ -246,6 +246,8 @@ static void nbd_size_set(struct nbd_device *nbd, loff_t blocksize, struct nbd_config *config = nbd->config; config->blksize = blocksize; config->bytesize = blocksize * nr_blocks; + if (nbd->task_recv != NULL) + nbd_size_update(nbd); } static void nbd_complete_rq(struct request *req)
