[PATCH 2/3] rcuperf: Insert space between flag and message consistently

From: SeongJae Park
Date: Sun Aug 21 2016 - 03:54:56 EST


Few output messages of rcuperf has no space between flag and start of
message while every other messages keeps a space consistently. It makes
output messages to be inconsistent and weird especially when it be read
by dmesg with color option enabled. This commit fixes the problem by
modifying a pr_alert() call and PERFOUT_STRING() macro function.
