| |
3.2.48-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Vivek Goyal <vgoyal@redhat.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.
