Now that requests can block other requests, we need to be careful to always clean up those blocked requests. Any time that we wait for a request, we might have other requests attached, and when we stop waiting, we must clean them up. If the lock was granted, the requests might have been moved to the new lock, though when merged with a pre-exiting lock, this might not happen. In all cases we don't want blocked locks to remain attached, so we remove them to be safe. Signed-off-by: NeilBrown <neilb@suse.com> Reviewed-by: J.

README
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.
