Seems we could remove the in-kernel version then? Besides better regression
testing, I'd assume the scripts in drgn repository can also handle ranges of
kernel versions and not the single one as of the given kernel commit (and
often not really due to undiscovered breakages) which IMHO is much for
useful for using these scripts and tools.
