Subject: [PATCH v1 2/4] tools, perf_event.h: Synchronize
Date: Tue, 14 Nov 2017 14:30:22 +0200	[thread overview]
Message-ID: <20171114123024.11517-3-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <20171114123024.11517-1-alexander.shishkin@linux.intel.com>

I've just added attr::suppress_aux bit to the kernel header, adding
it to the tools' header too.
