From c4b6014e8bb0c8d47fe5c71ebc604f31091e5d3f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 11 Jul 2016 10:28:48 -0300 Subject: tools: Add copy of perf_event.h to tools/include/linux/ We shouldn't use headers from the kernel sources directly, instead we should use the system's headers or in cases where that isn't possible, like with perf_event.h, where the introduction of kernel features such as perf_event_attr.{write_backwards,sample_max_stack} and PERF_EVENT_IOC_PAUSE_OUTPUT take some time to become available in /usr/include/linux/perf_event.h we need a copy. Do it and check for source code drift, emitting a warning when changes are detected.
