#1636971 — [PATCH 3/3] kernel-sched: Combine two seq_printf() calls into one in show_schedstat()

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 6 May 2017 21:26:19 +0200

Some data were put into a sequence by two separate function calls.
Print the same data by a single function call instead.

This issue was detected by using the Coccinelle software.
