Subject: [PATCH] trace-cmd: Fix create_recorder() path assignment
Date: Mon, 8 Feb 2021 19:36:01 -0500
Message-ID: <20210208193601.13d2772a@gandalf.local.home> (raw)

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()")
