Commit 228804a35caa tried to add a refcount check to gfs2_scan_glock_lru() to make sure that glocks that are still referenced cannot be freed. It failed to account for the bias state_change() adds to the refcount for held glocks, so held glocks are no longer removed from the glock cache, which can lead to out-of-memory problems. Fix that. (The inodes those glocks are associated with do get shrunk and do get pushed out of memory.) In addition, use the same eligibility check in gfs2_scan_glock_lru() and gfs2_dispose_glock_lru().

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.
