We can race where iscsi_session_recovery_timedout() has woken up the error handler thread and it's now setting the devices to offline, and session_recovery_timedout()'s call to scsi_target_unblock() is also trying to set the device's state to transport-offline. We can then get a mix of states. For the case where we can't relogin we want the devices to be in transport-offline so when we have repaired the connection __iscsi_unblock_session() can set the state back to running. Set the device state then call into libiscsi to wake up the error handler.

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.
