From 4064c3b86b289a866e801954bd9585c9281c0322 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 16 May 2018 14:51:18 -0400 Subject: [PATCH] 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: b8d12a8 ("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(+) diff --git a/drivers/block/nbd.c b/drivers/block/nbd.c index 9710a0c338b0a..b709abf3cb792 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) -- 2.39.5
