Since kernel 4.1 ftrace is supported as a new separate filesystem. It gets automatically mounted by the kernel under the old path /sys/kernel/debug/tracing. Because it lives now on a separate device some sepolicy rules need to be updated. This patch is doing that. Most of the rules are created based on a conversation happened on the SELinux Android mailing list: http://comments.gmane.org/gmane.comp.security.seandroid/2799 Note, that this also needs 3a343a1 from the 4.4 branch in kernel/common. Also note that when tracefs is auto mounted by the kernel, the kernel does not use the "mode" parameter specified to mount debugfs for tracefs. So an extra line like chmod 0755 /sys/kernel/debug/tracing is necessary in init.${ro.hardware}.rc after debugfs was mounted.
