The gfs2 evict code tries to upgrade the iopen glock from SH to EX. If the attempt to upgrade times out, gfs2 needs to tell dlm to cancel the lock request or it can deadlock. We also need to wake up the process waiting for the lock when dlm sends its AST back to gfs2.

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.
