From 4199bae10c49e24bc2c5d8c06a68820d56640000 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 15 Nov 2021 09:11:49 -0800 Subject: net: merge net->core.prot_inuse and net->core.sock_inuse net->core.sock_inuse is a per cpu variable (int), while net->core.prot_inuse is another per cpu variable of 64 integers. per cpu allocator tend to place them in very different places. Grouping them together makes sense, since it makes updates potentially faster, if hitting the same cache line. Signed-off-by: Eric Dumazet Signed-off-by: David S.
