Subject: [PATCH 03/43] perf tools: Get rid of unused 'swapped' parameter from perf_event__synthesize_sample()
Date: Tue, 23 Jan 2018 10:12:11 -0300	[thread overview]
Message-ID: <20180123131251.28197-4-acme@kernel.org> (raw)
In-Reply-To: <20180123131251.28197-1-acme@kernel.org>

From: Adrian Hunter <adrian.hunter@intel.com>

There is never a need to synthesize a 'swapped' sample, so all callers
to perf_event__synthesize_sample() pass 'false' as the value to
'swapped'. So get rid of the unused 'swapped' parameter.
