htree indexing and 64-bit file systems
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.
