From: Arnaldo Carvalho de Melo Date: Wed, 5 Jun 2019 13:53:06 +0000 (-0300) Subject: perf trace: Associate more argument names with the filename beautifier X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dea87bfb7b280e8b14519eb6b5e8bafbbf4c66f2;p=openwrt%2Fstaging%2Fblogic.git perf trace: Associate more argument names with the filename beautifier For instance, the rename* family uses "oldname", "newname", so check if "name" is at the end and treat it as a filename.
