From: Julia Lawall Date: Sun, 13 Oct 2024 20:16:49 +0000 (+0200) Subject: ipv4: replace call_rcu by kfree_rcu for simple kmem_cache_free callback X-Git-Tag: v6.13-rc1~135^2~313^2~4 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=497e17d807593bbeedc466029b30c2daa25004ba;p=thirdparty%2Fkernel%2Flinux.git ipv4: 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. Signed-off-by: Julia Lawall Reviewed-by: Eric Dumazet Acked-by: Paul E.
