[PATCH 0/3] Some tracing fixes.

[Jiaxing Wang <hello.wjx@gmail.com>]

In short:
  The first patch update instance_rmdir() to use tracefs_remove_recursive.
  The second one make tracing work when debugfs is not initialized, currently
we get an empty directory after mounting tracefs manually.
  The third one makes it possible to specify tracer specific options from
kernel parameter, like the following:
  
  ftrace=function ftrace_filter=kfree trace_options=func_stack_trace

Jiaxing Wang (3):
  tracing: Update instance_rmdir() to use tracefs_remove_recursive.
  tracing: Make tracing work when debugfs is not compiled or
    initialized.
  tracing: Apply tracer specific options from kernel command line.
