This patch fix SAS_QUEUE_FULL problem. The test situation is close port while running IO. In sas_eh_handle_sas_errors(), SCSI EH will free sas_task of the device if lldd_I_T_nexus_reset() return TMF_RESP_FUNC_COMPLETE or -ENODEV. But in our SAS driver, we only free slots of the device when the return value is TMF_RESP_FUNC_COMPLETE. So if the return value is -ENODEV, the slot resource will not free any more. As an solution, we should also free slots of the device in lldd_I_T_nexus_reset() if the return value is -ENODEV.

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.
