Prevent incrementing device->commands_outstanding for ioaccel command retries that are driver initiated. If the command goes through the retry path, the device->commands_outstanding counter has already accounted for the number of commands outstanding to the device. Only commands going through function hpsa_cmd_resolve_events decrement this counter. - ioaccel commands go to either HBA disks or to logical volumes comprised of SSDs. The extra increment is causing device resets to hang. - Resets wait for all device outstanding commands to complete before returning. Replace unused field abort_pending with retry_pending. This is a maintenance driver so these changes have the least impact/risk.

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.
