Lee Duncan a656183e6c scsi: libiscsi: Hold back_lock when calling iscsi_complete_task
If there is an error queueing an iscsi command in iscsi_queuecommand(), for
example if the transport fails to take the command in
sessuin->tt->xmit_task(), then the error path can call
iscsi_complete_task() without first aquiring the back_lock as
required. This can lead to things like ITT pool can get corrupt, resulting
in duplicate ITTs being sent out.

The solution is to hold the back_lock around iscsi_complete_task() calls,
and to add a little commenting to help others understand when back_lock
must be held.

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.
