Correct a rare case where in a LUN reset occurs on a device and I/O requests for other devices persist in the driver's internal request queue. Part of a LUN reset involves waiting for our internal request queue to empty before proceeding. The internal request queue contains requests not yet sent down to the controller. We were clearing the requests queued for the LUN undergoing a reset, but not all of the queued requests. Causing a hang. For all requests in our internal request queue: Complete requests with DID_RESET for queued requests for the device undergoing a reset. Complete requests with DID_REQUEUE for all other queued requests.

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 reStructuredText 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.
