MarsSeed [1] filed a deletion request for linux-api-headers-git [2]: Not a VCS package, as it uses a fixed commit. Abandoned.
If needed, a '-dev' package using a fixed snapshot could be created instead of this. Meanwhile, Arch/core repo carries a stable linux-api-headers package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/linux-api-headers-git/
