Hello David,

after pulling these patchset in net, you should hit a conflict while trying to
merge net into net-next. The conflict is caused by the renaming patches that you
already have in the next tree.

Here are our instructions about how to solve it. Hope they will help.
Thank you.


Conflict 1:
<<<<<<<
	orig_entry = container_of(rcu, struct batadv_tt_orig_list_entry, rcu);
	atomic_dec(&orig_entry->orig_node->tt_size);
	batadv_orig_node_free_ref(orig_entry->orig_node);
=======
	orig_entry = container_of(rcu, struct tt_orig_list_entry, rcu);
	orig_node_free_ref(orig_entry->orig_node);
>>>>>>>

Resolves to:
=======
	orig_entry = container_of(rcu, struct batadv_tt_orig_list_entry, rcu);
	batadv_orig_node_free_ref(orig_entry->orig_node);
=======


Conflict 2:
<<<<<<<
	call_rcu(&orig_entry->rcu, batadv_tt_orig_list_entry_free_rcu);
=======
	/* to avoid race conditions, immediately decrease the tt counter */
	atomic_dec(&orig_entry->orig_node->tt_size);
	call_rcu(&orig_entry->rcu, batadv_tt_orig_list_entry_free_rcu);
>>>>>>>

Resolves to:
=======
	/* to avoid race conditions, immediately decrease the tt counter */
	atomic_dec(&orig_entry->orig_node->tt_size);
	call_rcu(&orig_entry->rcu, batadv_tt_orig_list_entry_free_rcu);
=======


Conflict 3:
<<<<<<<
	struct batadv_tt_local_entry *tt_local_entry = NULL;
	struct batadv_tt_global_entry *tt_global_entry = NULL;
	bool ret = true;
=======
	struct tt_local_entry *tt_local_entry = NULL;
	struct tt_global_entry *tt_global_entry = NULL;
	bool ret = false;
>>>>>>>

Resolves to:
=======
	struct batadv_tt_local_entry *tt_local_entry = NULL;
	struct batadv_tt_global_entry *tt_global_entry = NULL;
	bool ret = false;
=======


Conflict 4:
<<<<<<<
	if (_batadv_is_ap_isolated(tt_local_entry, tt_global_entry))
=======
	if (!_is_ap_isolated(tt_local_entry, tt_global_entry))
>>>>>>>

Resolves to:
=======
	if (!_batadv_is_ap_isolated(tt_local_entry, tt_global_entry))
=======
