Control: reassign -1 grub-xen-host 2.12-7
Control: affects -1 src:linux

grub2 lacks any support to decompress zstd kernels.  This affects
booting xen pv via grub2, as there it needs to decompress the kernel
first.  grub2 itself contains support for zstd already, it just isn't
plumbed into the generic io filter via grub_file_filter_register

Relevant change to the Linux package:
