Kamilcuk [1] filed a deletion request for linux-enablezfsbuild [2]: This was a temporary linux kernel for building zfs module when it couldn't be done because two symbols were GPL. Zfsonlinux has been patches since then, so... this should just be removed, it's unneeded. [1] https://aur.archlinux.org/account/Kamilcuk/ [2] https://aur.archlinux.org/pkgbase/linux-enablezfsbuild/
