From f4a74fcbfd943e128bbd464dc31b4405e1514d63 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 27 Dec 2018 10:56:12 -0300 Subject: perf trace: Rename thread_thread->paths to thread_trace->files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit So that we can add more per file attributes besides the pathname, such as which ioctl beautifier to use, for cases such as the sound and usbdeffs ioctls, that both use the 'U' command, so we have to differentiate at the major number for the device file.
