From 81898ef1303d8fb5a3256b09b3140b4eee83dad8 Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Tue, 2 Feb 2021 12:09:05 -0800 Subject: [PATCH] tools headers uapi: Update tools's copy of linux/perf_event.h To get the changes in these csets: 2a6c6b7d7ad346f0 ("perf/core: Add PERF_SAMPLE_WEIGHT_STRUCT") 61b985e3e775a3a7 ("perf/x86/intel: Add perf core PMU support for Sapphire Rapids") 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 Committer notes: Picked by hand as I had already merged the MMAP buildid patch that also touches perf_event.h and is also only in {acme,tip}/perf/core, not yet upstream.
