Subject: [PATCH 44/63] perf trace: Add a prefix member to the strarray class
From: Arnaldo Carvalho de Melo <acme@...hat.com>
So that the user, in an upcoming patch, can select printing it to get
the full string as used in the source code, not one with a common prefix
chopped off so as to make the output more compact.
