"lsattr <dir>" will show it.  Note that it will only ever be set on
directories that are larger than a single disk block.

# lsattr -d d1

That's the great thing about htree - you don't need to do anything to turn
it off.  The on-disk format is exactly the same as without htree, and the
first time you modify the directory it will clear the per-directory htree
flag.
