The purpose of flush routine is to cleanup I/Os to the firmware and complete them to scsi middle layer. This routine is invoked before connection is uploaded because of rport going away. - Don't process any I/Os, aborts, TMFs coming when flush in progress. - Add flags to handle cleanup and release of I/Os because flush can prematurely complete I/Os. - Original command can get completed to driver when cleanup for same is posted to firmware, handle this condition. - Modify flush to handle I/Os in all the states like abort, TMF, RRQ and timeouts.

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.
