[PATCH 0/3] netlink: per-protocol bind fixup/enhancement set

This set provides a way for per-protocol bind functions to signal an error and to be able to clean up after themselves. The first patch has already been accepted, but is included just in case to avoid a merge error. The second patch adds the per-protocol bind return code to signal to the netlink code that no further processing should be done and to undo the work already done. This rev has fixed DaveM's last issue and flattened the intentation as requested by Patrick McHardy by two by reworking the logic. The third provides a way per protocol to undo actions on DROP. Thanks for the feedback.
