Subject: [PATCH v2 6/7] tools headers UAPI: Sync pkt_sched.h with the kernel sources
Date:   Fri, 21 May 2021 01:58:47 -0700
Message-Id: <20210521085849.37676-7-joerichey94@gmail.com>

From: Joe Richey <joerichey@google.com>

It looks like this process isn't automatic for some reason.

This prevents some perf tools warnings and removes use of the
BIT() macro which isn't present for UAPI headers.
