[ Upstream commit ee2be7d7c7f32783f60ee5fe59b91548a4571f10 ] Function gfs2_glock_queue_put() puts a glock reference by enqueuing glock work instead of putting the reference directly. This ensures that the operation won't sleep, but it is costly and really only necessary when putting the final glock reference. Replace it with a new gfs2_glock_put_async() function that only queues glock work when putting the last glock reference.

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.
