Introduce a new LM_FLAG_NODE_SCOPE glock holder flag: when taking a glock in LM_ST_EXCLUSIVE (EX) mode and with the LM_FLAG_NODE_SCOPE flag set, the exclusive lock is shared among all local processes who are holding the glock in EX mode and have the LM_FLAG_NODE_SCOPE flag set. From the point of view of other nodes, the lock is still held exclusively. A future patch will start using this flag to improve performance with rgrp sharing.

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.
