xfrm: Revert false event eliding commits.
As reported by Alexey Dobriyan: -------------------- setkey now takes several seconds to run this simple script and it spits "recv: Resource temporarily unavailable" messages. #!/usr/sbin/setkey -f flush; spdflush; add A B ipcomp 44 -m tunnel -C deflate; add B A ipcomp 45 -m tunnel -C deflate; spdadd A B any -P in ipsec ipcomp/tunnel/192.168.1.2-192.168.1.3/use; spdadd B A any -P out ipsec ipcomp/tunnel/192.168.1.3-192.168.1.2/use; -------------------- Obviously applications want the events even when the table is empty. So we cannot make this behavioral change. Signed-off-by: David S. Miller <davem@davemloft.net>
