Hi, here is my v4 patch-set update to the v3 RFC submitted on Nov 27th. When an active virtio block device is hot-unplugged from a KVM guest, affected guest user applications are not aware of any errors that occur due to the lost device. This patch-set adds code to avoid further request queueing when a lost block device is detected, resulting in appropriate error info. Additionally a potential

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just
