From: "Steven Rostedt (VMware)" <>

The assignment of path was suppose to copy the dir variable that is returned
from tracefs_tracing_dir(), but instead the path copied itself.

This broke the communication between host and guest as well as networking.

Fixes: b8498696e0 ("trace-cmd: Use tracefs_tracing_dir() instead of tracefs_find_tracing_dir()")
