   1 ext4 crypto: enables delayed allocation

   5 I had delayed allocation disabled because it seemed like the
   6 conservative/safe thing to do during initial development of the
   7 feature. However, it seems that we don't have much (if anything) to do
   8 to support delayed allocation with encryption, so I'm re-enabling that
   9 code path for further test and development.
