Subject: [PATCH 16/35] perf record: Rename 'perf_record' to plain 'record'
From: Arnaldo Carvalho de Melo <acme@...hat.com>
Its a local struct and the functions use the __ separator from the class
name to the method name, so its unlikely that this will clash with other
namespaces.
Save some typing then.
