Subject: [PATCH 1/9] tools headers uapi: Update tools's copy of linux/perf_event.h
Date: Tue,  2 Feb 2021 12:09:05 -0800	[thread overview]
Message-ID: <1612296553-21962-2-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1612296553-21962-1-git-send-email-kan.liang@linux.intel.com>

From: Kan Liang <kan.liang@linux.intel.com>

To get the changes in:

    commit 2a6c6b7d7ad3 ("perf/core: Add PERF_SAMPLE_WEIGHT_STRUCT")

This cures the following warning during perf's build:

        Warning: Kernel ABI header at
'tools/include/uapi/linux/perf_event.h' differs from latest version at
'include/uapi/linux/perf_event.h'
        diff -u tools/include/uapi/linux/perf_event.h
include/uapi/linux/perf_event.h
