[PATCH 0/4] kdbus: name registry cleanup patches

[Daniel Mack <daniel@zonque.org>]

Hi Greg,

Here are some patches for kdbus-next David and I prepared:

* The first one cleans up the name registry code and brings the name
  queuing logic in sync with what the DBus spec requires. We were off
  in some small details concerning flags updates of already queued
  names.

* The second one adds two more return flags in the name queuing logic,
  so userspace has better ways of knowing what effect a name acquisition
  call had.

* Number three is a small cleanup that makes sure we never return
  negative return codes from ioctls if we modified any internal state.
  This is a rule all other command dispatchers follow as well.

* The last one adds more selftests for the name registry, covering the
  newly added flags.


None of these patches is critical, and everything has been running well
on our machines for a while.


Thanks,
Daniel
