selinux: enable genfscon labeling for tracefs
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. Signed-off-by: Jeff Vander Stoep <jeffv@google.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: Paul Moore <paul@paul-moore.com>
