[PATCH net 00/12] net: shaper: fix various minor bugs

[Jakub Kicinski <kuba@kernel.org>]

Fix various minor bugs in the net shaper API.

First 4 changes are a bit hairy. The readers are currently under
RCU so we need to be careful how we update and insert the nodes.
Patch 4 is a bit of a cop-out. Pre-allocating replacement nodes
is complex. If the workaround is not acceptable I'd seriously
consider making the readers take the instance lock.

Only other patch of note is patch 10. We want to add a Netlink
policy check on the handle ID. This necessitates patch 9.

The rest are simple and self-explanatory.
