Subject: [PATCH 13/23] perf bench mem: Reorganize the code a bit
Date: Mon, 19 Oct 2015 18:39:24 -0300 [thread overview]
Message-ID: <1445290774-13344-14-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1445290774-13344-1-git-send-email-acme@kernel.org>
From: Ingo Molnar <mingo@kernel.org>
Reorder functions a bit, so that we synchronize the layout of the
memcpy() and memset() portions of the code.
This improves the code, especially after we'll add an strlcpy() variant
as well.
