From 860b642b9c33ea4a6ae2f416607b0b98a9d11bb0 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Tue, 3 Jul 2018 15:42:52 -0700 Subject: [PATCH] net/sched: Allow creating a Qdisc watchdog with other clocks This adds 'qdisc_watchdog_init_clockid()' that allows a clockid to be passed, this allows other time references to be used when scheduling the Qdisc to run.
