Al,
I know that you do not like the releasing of the parent i_mutex lock.
But it is no different than what we do today, except that we move the
release out of the tracing code and into the tracefs code.
This still gives us the separate tracefs filesystem that will let
users mount it without needing to mount debugfs, so I want to get this
into 3.20.
These are the patches that I plan on submitting, and will soon be adding
to my linux-next branch, to be included in linux-next.
