From aa70d2d16f280efe8aa52afc25a33b2ec8d346b6 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 6 Mar 2024 16:00:23 +0000 Subject: net: move skbuff_cache(s) to net_hotdata skbuff_cache, skbuff_fclone_cache and skb_small_head_cache are used in rx/tx fast paths. Move them to net_hotdata for better cache locality.
