Subject: [for-linus][PATCH 0/5] tracing: Updates for 5.16-rc5

Ftrace and tracefs fixes:

 - Have tracefs honor the gid mount option

 - Have new files in tracefs inherit the parent ownership

 - Have direct_ops unregister when it has no more functions

 - Properly clean up the ops when unregistering multi direct ops

 - Add a sample module to test the multiple direct ops
