This list entry\nitself was one of the references which need to be dropped at the same time\nvia batadv_claim_put().\n\nBut the batadv_claim_put() must not be done before the last access to the\nclaim object in this function. Otherwise the claim might be freed already\nby the batadv_claim_release() function before the list entry was dropped.",
