    IB/cm: Remove now useless rcu_lock in dst_fetch_ha · 92ebb6a0
    Jason Gunthorpe authored Jun 27, 2018
    This lock used to be protecting a call to dst_get_neighbour_noref,
    however the below commit changed it to dst_neigh_lookup which no longer
    requires rcu.
    
    Access to nud_state, neigh_event_send or rdma_copy_addr does not require
    RCU, so delete the lock.
    
    Fixes: 02b61955
    
     ("infiniband: Convert dst_fetch_ha() over to dst_neigh_lookup().")
