2008-11-25netns xfrm: per-netns state GC listAlexey Dobriyan2-3/+4
km_waitq is going to be made per-netns to disallow spurious wakeups in __xfrm_lookup(). To not wakeup after every garbage-collected xfrm_state (which potentially can be from different netns) make state GC list per-netns.

This is done to get a) simple "something leaked" check b) cover possible DoSes when other netns puts many, many xfrm_states onto a list. c) not miss "alien xfrm_state" check in some of list iterators in future.
