This patch : 1) Remove a dst leak if DST_NOCACHE was set on dst Fix this by holding a reference only if dst really cached. 2) Remove a lockdep warning in __tunnel_dst_set() This was reported by Cong Wang. 3) Remove usage of a spinlock where xchg() is enough 4) Remove some spurious inline keywords. Let compiler decide for us.
