I'm not sure how this happened but the patch that was intended to fix abort
handling was incomplete. This patch fixes that patch as follows:
- If aborting the SCSI command failed, wait until the SCSI command
completes.
- Return SUCCESS instead of FAILED if an abort attempt races with SCSI
command completion.
- Since qla2xxx_eh_abort() increments the sp reference count by calling
sp_get(), decrement the sp reference count before returning.

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.
