2.6.18-rc4-mm3: BUG: warning at include/net/dst.h:154/dst_release()

[Valdis.Kletnieks@vt.edu]

Seeing this a lot on 2.6.18-rc4-mm3 with 2 different stack tracebacks
(one for received packets, other for sending).  I already picked up the
fix for the ^ / confusion in fib_rules.c and that didn't help matters.
