 Currently, if a corrupted directory entry with rec_len=0 is encountered,
 we still trust that the data is valid. This can cause an infinite loop
 in htree_dirblock_to_tree() since the iteration loop will never make any
 progress.

Actually, I think Eric Sandeen was working on similar fixes already, and
instead of doing a per-item check each time we look at the entry it does
a full-block check the first time it is read (as ext2 does).

 This fixes the problem described at:

Would also be good to CC linux-ext4, where the ext3 maintainers live.
Hmm, maybe we need to update MAINTAINERS with the new list address?
