From: Arnaldo Carvalho de Melo Date: Thu, 17 Nov 2011 14:19:04 +0000 (-0200) Subject: perf report: Group options in a struct X-Git-Tag: v3.3-rc1~192^2~64 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=fa372aae335c6dfbe808d5a728fe10cd202dde45;p=~emulex%2Finfiniband.git perf report: Group options in a struct Paving the way to remove these globals when we change the perf_event_ops to receive as a first parameter a pointer to a perf_event_ops that will then provide access to perf_report via container_of.
