Subject: [PATCH 14/28] perf script: Add newline after uregs output
Date: Thu, 22 Nov 2018 00:35:57 -0300 [thread overview]
Message-ID: <20181122033611.15890-15-acme@kernel.org> (raw)
In-Reply-To: <20181122033611.15890-1-acme@kernel.org>
From: Milian Wolff <milian.wolff@kdab.com>
This change makes it much easier to easily distinguish between
consecutive samples by keeping the empty line between them, like we see
when we do not enable uregs output.
