I'll go back and look at that, but in general it's hard to transition
from ext2fs_block_iterate2() ext2fs_block_iterate3() independently
because the iterate function has to convert to 64-bit at the same time
(or else you have to write complex and ugly glue code which lives for
exactly one revision).

Yes, in check_ext_attr() in pass1.c (and in process_bad_inode() in
pass2.c).

Fine by me. I'll include them with your "*_lo" rename suggestions if
Ted agrees.
