File perf-top-set-display-thread-comm-to-help-with-debugging.patch of Package perf.23962

From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Tue, 6 Aug 2019 11:20:42 -0300
Subject: perf top: Set display thread COMM to help with debugging
Git-commit: 1205a2719e52b6b52e0f9c0011554419da0377a0
Patch-mainline: v5.4-rc1
References: jsc#SLE-12726

When we want to attach just to the thread that updates the display it
helps having its COMM stand out, so change it from the default "perf" to
"perf-top-UI".
