Pull probes fixes from Masami Hiramatsu:
- Fix fprobe's rethook release issues:
- Release rethook after ftrace_ops is unregistered so that the
rethook is not accessed after free.
- Stop rethook before ftrace_ops is unregistered so that the
rethook is NOT used after exiting unregister_fprobe()
- Fix eprobe cleanup logic. If it attaches to multiple events and
failes to enable one of them, rollback all enabled events correctly.
- Fix fprobe to unlock ftrace recursion lock correctly when it missed
by another running kprobe.
- Cleanup kprobe to remove unnecessary NULL.
- Cleanup kprobe to remove unnecessary 0 initializations.

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 Restructured Text 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.
