Subject: [PATCH] selinux: enable genfscon labeling for tracefs
Date: Tue, 20 Jun 2017 09:35:33 -0700	[thread overview]
Message-ID: <20170620163533.2558-1-jeffv@google.com> (raw)

In kernel version 4.1, tracefs was separated from debugfs into its
own filesystem. Prior to this split, files in
/sys/kernel/debug/tracing could be labeled during filesystem
creation using genfscon or later from userspace using setxattr. This
change re-enables support for genfscon labeling.
