About patches which:

  - Are rebased to current upstream

  - Addressed the outstanding review comments

  - Have proper documentation in the changelog of the user space visible
    ABI changes why it does not break any existing usage and having the
    relevant people who maintain tools which utilize the affected
    interfaces Cc'ed on submission.

  - Made sure that the cleanups I did when merging them initially have
    been picked up. I'm not going to waste another couple of days on
    this mess just to revert it because it hadn't seen any serious
    testing in development.

Thanks,
