John Keeping 5a74a75fc3 ftrace: Mark get_lock_parent_ip() __always_inline
commit ea65b41807a26495ff2a73dd8b1bab2751940887 upstream.

If the compiler decides not to inline this function then preemption
tracing will always show an IP inside the preemption disabling path and
never the function actually calling preempt_{enable,disable}.

README

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.
