virtio-blk: Call revalidate_disk() upon online disk resize
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. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
