From: Arnaldo Carvalho de Melo Date: Tue, 3 Mar 2015 15:37:54 +0000 (-0300) Subject: perf tools: tool->finished_round() doesn't need perf_session X-Git-Tag: firefly_0821_release~176^2~1816^2~72^2~20 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d704ebdae4aaeec89180dcfd0ca74e5bba318853;p=firefly-linux-kernel-4.4.55.git perf tools: tool->finished_round() doesn't need perf_session It is all about flushing the ordered queue or piping it thru, no need for a perf_session pointer.
