I've just been ignoring htree indexing for now, but the regression
failure in Ted's rebased 64bit tree looks suspiciously htree-related.
What's the interaction between htree and 64 bit file systems? What
needs to change, if anything?

There shouldn't be any. The block numbers used in htree are logical
block numbers (i.e., block 0 is the first block in the directory,
block 1 is the 2nd block i the directory, etc.)

What if the directory is REALLY HUGE? :) Say >68.719.476.736 files.
Can ext4 64bit have directories >8TiB?

No, ext4 directories are limited to 2TB. Htree directories are
currently limited to a depth of two, which for smaller block sizes
will be more of limitation than the maximum size limitation.
