Before this patch, when a glock was locked by function gfs2_glock_nq_init, it initialized the holder gh_ip (return address) as gfs2_glock_nq_init. That made it extremely difficult to track down problems because many functions call gfs2_glock_nq_init. This patch changes the function so that it saves gh_ip from the caller of gfs2_glock_nq_init, which makes it easy to backtrack which holder took the lock.

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.
