Re: [libvirt] [PATCH] rbd: Allow shrinking and deltas when resizing RBD volumes

Modify virCheckFlags that it accepts both VIR_STORAGE_VOL_RESIZE_DELTA and VIR_STORAGE_VOL_RESIZE_SHRINK as valid flags for resizing RBD volumes. This still does not solve the problem where RBD volumes can't be shrinked using libvirt. The allocation and capacity of RBD volumes are equal for a RBD volume and this makes libvirt think the volume is fully allocated and therefor can't be shrinked.
