[ Upstream commit c81ef0ed4477c637d1f1dd96ecd8e8fbe18b7283 ] Since the SCSI core does not reuse the tag of the SCSI command that is being aborted by .eh_abort() before .eh_abort() has finished it is not necessary to check from inside that callback whether or not the SCSI command has already completed. Instead, rely on the firmware to return an error code when attempting to abort a command that has already completed. Additionally, rely on the firmware to return an error code when attempting to abort an already aborted command. In qla2x00_abort_srb(), use blk_mq_request_started() instead of sp->completed and sp->aborted.

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.
