alloc_inode_sb() was introduced in mainline v5.18-rc1, and aufs5.x-rcN branch supports it. Aufs5.15.5 should not contain such code calling alloc_inode_sb().

Are you sure that your aufs5.15.5 code has alloc_inode_sb() call?

After double checking, looks like there was an error in the PKGBUILD with an improperly set git checkout command
