As same as fprobe, register tracepoint stub function only when enabling tprobe events. The major changes are introducing a list of tracepoint_user and its lock, and tprobe_event_module_nb, which is another module notifier for module loading/unloading. By spliting the lock from event_mutex and a module notifier for trace_fprobe, it solved AB-BA lock dependency issue between event_mutex and tracepoint_module_list_mutex.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
