/* Me, Vladimir Serbinenko, hereby I add this module check as per new
GNU module policy. Note that this license check is informative only.
Modules have to be licensed under GPLv3 or GPLv3+ (optionally
multi-licensed under other licences as well) independently of the
presence of this check and solely by linking (module loading in GRUB
constitutes linking) and GRUB core being licensed under GPLv3+.
Be sure to understand your license obligations.
