From c3f7c9397609705ef848cc98a5fb429b3e90c3c4 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 16 May 2018 14:51:18 -0400 Subject: nbd: update size when connected 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 Signed-off-by: Jens Axboe --- drivers/block/nbd.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers') 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) -- cgit v1.2.3
