Issue - Driver returns DID_NO_CONNECT when unload is in progress, indicated using instance->unload flag. In case of dynamic unload of driver, this flag is set before calling scsi_remove_host(). While doing manual driver unload, user will see lots of prints for Sync Cache command with DID_NO_CONNECT status. Fix - Set the instance->unload flag after scsi_remove_host(). Allow device removal process to be completed and do not block any command before that. SCSI commands (like SYNC_CACHE) are received (as part of scsi_remove_host) by driver during unload will be submitted further down to the drives.

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.
