Date: Wed, 26 Jun 2013 03:35:58 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Jens Axboe" <axboe@...nel.dk>, "Vivek Goyal" <vgoyal@...hat.com> Subject: [11/26] virtio-blk: Call revalidate_disk() upon online disk resize 3.2.48-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Vivek Goyal <vgoyal@...hat.com> commit e9986f303dc0f285401de28cf96f42f4dd23a4a1 upstream. If a virtio disk is open in guest and a disk resize operation is done, (virsh blockresize), new size is not visible to tools like "fdisk -l". This seems to be happening as we update only part->nr_sects and not bdev->bd_inode size. Call revalidate_disk() which should take care of it. I tested growing disk size of already open disk and it works for me.
