Add a new optional routine, eh_should_retry_cmd(), in scsi_host_template that allows the transport to decide if a cmd is retryable. Return true if the transport is in a state the cmd should be retried on. Update scmd_eh_abort_handler() and scsi_eh_flush_done_q() to both call scsi_eh_should_retry_cmd() to check whether the command needs to be retried. The above changes were based on a patch by Mike Christie.

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.
