[PATCH 10/10] perf tools: Finish the removal of 'self' arguments
From: Arnaldo Carvalho de Melo
Date: Tue Nov 05 2013 - 15:10:45 EST
From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
They convey no information, perhaps I was bitten by some snake at some
point, complete the detox by naming the last of those arguments more
sensibly.
