pve-qemu-qoup/debian/patches/pve/0013-PVE-Up-qemu-img-dd-add-n-skip_create.patch
Stefan Reiter 60ae3775bf update to QEMU 5.1
No major semantic changes, mostly just deprecations and changed function
signatures. Drop the extra/ patches, as they have been applied upstream.

The added extra/ patch was accepted upstream[0] but has not been picked
up for 5.1. It is required for non-4M aligned backups to work with PBS.
