Subject: [PATCH 06/23] libperf: Add PERF_RECORD_HEADER_BUILD_ID 'struct build_id_event' to perf/event.h
Date:   Wed, 28 Aug 2019 15:57:00 +0200
Message-Id: <20190828135717.7245-7-jolsa@kernel.org>

Precedence: bulk

Move the PERF_RECORD_HEADER_BUILD_ID event definition to libperf's event.h.

In order to keep libperf simple, we switch 'u64/u32/u16/u8'
types used events to their generic '__u*' versions.

Adding the fix value for build_id variable,
because it will never change.
