  As mentioned 'inline with vfs layer' I mean to say to use
  fs/crypto KPIs. Which I haven't seen what parts of the code
  from ext4 was made as generic KPIs. If that's getting stuff
  correct in the encryption related, I think it would here as well.

  Internal to btrfs - I had challenges to get the extents encoding
  done properly without bailout, and the test plan. Which I think
  is addressed here in this code. as mentioned.

  Honestly I agree. I even suggested but I had no choice.


PS:
  Pls, feel free to flame on the (raid) patches if its not correct,
  because its rather more productive than no reply.


Thanks, Anand
