These all look fine to me, and I have no problem with them going through
the network tree as that will most likely be the easiest way due to any
potential merge issues.

David, feel free to add an:
	Acked-by: Greg Kroah-Hartman <gregkh@xxxxxxx>

to these patches and take them through your tree if that is ok with you.
If not, I can also always take them through mine, it's your choice.
