From 32f8c816b92e5f7d556ca2f7f17082ce8c8286f0 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Tue, 23 Aug 2022 10:46:46 -0700 Subject: net: Fix data-races around netdev_max_backlog. [ Upstream commit 5dcd08cd19912892586c6082d56718333e2d19db ] While reading netdev_max_backlog, it can be changed concurrently. Thus, we need to add READ_ONCE() to its readers. While at it, we remove the unnecessary spaces in the doc. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Kuniyuki Iwashima Signed-off-by: David S.
