Subject: Avoid rec_len overflow with 64KB block size

   Hello,

  when converting ext4 directories to pagecache I just came over
Takashi's patch preventing overflowing of rec_len. Looking over the
patch - can't we do it more elegantly by using say 0xffff instead of 64K
and perform conversion (using some helper) at the moment we read / store
rec_len? That would be IMHO more transparent than current approach (at
least it took me some time to understand what's going on with the
current patch when I was looking at the code)...

								Honza
