The following commit has been merged in the batadv/net-next branch: commit 356c81b6c494a359ed6e25087931acc78c518fb9 Author: Julia Lawall Julia.Lawall@inria.fr Date: Sun Oct 13 22:16:53 2024 +0200

batman-adv: replace call_rcu by kfree_rcu for simple kmem_cache_free callback

Since SLOB was removed and since commit 6c6c47b063b5 ("mm, slab: call kvfree_rcu_barrier() from kmem_cache_destroy()"), it is not necessary to use call_rcu when the callback only performs kmem_cache_free. Use kfree_rcu() directly.

The changes were made using Coccinelle.
