From 4282d60689d4f21b40692029080440cc58e8a17d Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Tue, 20 Jan 2015 11:36:55 -0500 Subject: tracefs: Add new tracefs file system Add a separate file system to handle the tracing directory. Currently it is part of debugfs, but that is starting to show its limits. One thing is that in order to access the tracing infrastructure, you need to mount debugfs. As that includes debugging from all sorts of sub systems in the kernel, it is not considered advisable to mount such an all encompassing debugging system. Having the tracing system in its own file systems gives access to the tracing sub system without needing to include all other systems. Another problem with tracing using the debugfs system is that the instances use mkdir to create sub buffers. debugfs does not support mkdir from userspace so to implement it, special hacks were used. By controlling the file system that the tracing infrastructure uses, this can be properly done without hacks.
