Shrinking a disk accidentally equals data loss and thus very bad time
for anyone mis-typing.
This series adds a new flag to virDomainBlockResize to prevent such a
thing if the user only intends to extend the disk.
In virsh I've went a bit further and actually change the behaviour of
'virsh blockresize' to use the new feature if available to prevent
mishaps.
Peter Krempa (6):
virDomainBlockResizeFlags: Convert to prefix-style docs
API/qemu: Introduce 'VIR_DOMAIN_BLOCK_RESIZE_EXTEND' for
'virDomainBlockResize'
virsh: blockresize: Introduce '--extend' flag
API: Introduce 'VIR_DOMAIN_BLOCK_RESIZE_PROBE_FLAGS' for
'virDomainBlockResize'
virsh/virt-admin: Add possibility to probe for new arguments
virsh: blockresize: Use VIR_DOMAIN_BLOCK_RESIZE_EXTEND when available
and introduce --allow-shrink
