I noticed a "scheduling while atomic" problem in the event caching
"replace notify chain by function pointer" patch. It seems that
gfp_any(), which is used by nfnetlink_send(), returns GFP_KERNEL inside
a RCU read-side lock section, that's invalid. Moreover, this triggers a
backtrace when using very small buffers and making lots of requests from
user-context (we hit schedule() due to __GFP_WAIT in the netlink code).

Patrick, just to let you know in case that you look at these patches. I
have fixed this here. I'll resend these patches once nf-next-2.6 is open.
