From 642978981ec8a79da00828c696c58b3732b993a6 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 24 Nov 2022 12:07:22 +0000 Subject: kselftest/arm64: Set test names prior to starting children Since we now flush output immediately on starting children we should ensure that the child name is set beforehand so that any output that does get flushed from the newly created child has the name of the child attached.
