Subject: [PATCH 00/15] perf tools: Cleanup filesystem api

hi,
this patchset moves all filesystem we use under
api/fs/fs.c framework and adds new tracing_path
object to get tracing area (path).

It unifies the way we use debugfs/tracefs paths
and removes some redundant code.

It's base for the tracepoint parsing error reporting
I posted recently.
