As I said in our private email exchange some months ago, I don't
think this is the right way to be doing this. For example, if you use
an alternative tool (such as btrfs-gui) which uses the ioctls
directly, you've lost that logging information.

  I agree with that Hugo. Thanks. These changes are partly for
  the same reason.

    Keeping a log of what's been done to the FS is much better done by
extending the available logging in the kernel

  Could you please point out the modules you are talking about.
  I reviewed some but just in case if I have missed out any.



Thanks,  Anand
