From 454bbde8f0d465e93e5a3a4003ac6c7e62fa4473 Mon Sep 17 00:00:00 2001 From: Menglong Dong Date: Wed, 9 Oct 2024 10:28:19 +0800 Subject: [PATCH] net: skb: add pskb_network_may_pull_reason() helper Introduce the function pskb_network_may_pull_reason() and make pskb_network_may_pull() a simple inline call to it. The drop reasons of it just come from pskb_may_pull_reason. Signed-off-by: Menglong Dong Reviewed-by: Simon Horman Signed-off-by: David S.
