So I reviewed all of the patches, most of them look good. Some comments:
 - Please justify your changes in the commit-message. Always.
 - Please don't split patches based on modified functions. If you fix
typos, do them subsystem-wide. If you fix common errors like "don't
init 'name' to NULL before calling kdbus_pin_dst()", then please do
that for all functions. In other words, group your changes logically,
not based on location.
 - If you do cleanups, explain why you do them. I commented on some of
the changes, which IMO reduce readability.

Anyway, looks good.

Thanks a lot!
David
