We set the max_active iSCSI EH works to 1, so all work is going to execute in order by default. However, userspace can now override this in sysfs. If max_active > 1, we can end up with the block_work on CPU1 and iscsi_unblock_session running the unblock_work on CPU2 and the session and target/device state will end up out of sync with each other. This adds a flush of the block_work in iscsi_unblock_session.

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.
