[ Upstream commit 9029a72500b95578a35877a43473b82cb0386c53 ] This is to fix SYNC CACHE and START STOP command failures with DID_NO_CONNECT during driver unload. In driver's IO submission patch (i.e. in driver's .queuecommand()) driver won't allow any SCSI commands to the IOC when ioc->remove_host flag is set and hence SYNC CACHE commands which are issued to the target drives (where write cache is enabled) during driver unload time is failed with DID_NO_CONNECT status. Now modified the driver to allow SYNC CACHE and START STOP commands to IOC, even when remove_host flag is set.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
