I think there are two interfaces that should handle nearly all of our journal block mapping needs. The functions that issue bio requests directly tend to use ext4_get_block*() functions, and functions which use the buffer cache uses submit_bh() (typically via ext4_getblk). There will probably be a few exceptions, but I don't think this should be an intractable problem.
