      xfrm: state: do not acquire lock in get_mtu helpers · b3b73b8e
      Florian Westphal authored
      Once flow cache gets removed the mtu initialisation happens for every skb
      that gets an xfrm attached, so this lock starts to show up in perf.
      
      It is not obvious why this lock is required -- the caller holds
      reference on the state struct, type->destructor is only called from the
      state gc worker (all state structs on gc list must have refcount 0).
      
      xfrm_init_state already has been called (else private data accessed
      by type->get_mtu() would not be set up).
      
      So just remove the lock -- the race on the state (DEAD?) doesn't
      matter (could change right after dropping the lock too).
