メモ
- No longer part of debugfs
- But all (psuedo) dirs and files the same
メモ
- Added in Linux 4.1, by Steve Rostedt
- Used by ftrace
- Instead of debugfs (usually Linux/sys/kernel/debug/tracing), tracing has now its own file system, under Linux/sys/kernel/tracing?
- To be compatible with old systems, it is also mounted under debugfs
- New include file linux/tracefs.h?
- ftrace and perf use it
- No changes in functionality
