Sometimes it is required to know when the controller reset has completed and also if it has completed successfully. For such places, we call hisi_sas_controller_reset() directly before. That may lead to multiple calls to this function. This patch create a per-reset structure which contains a completion structure and status flag to know when the reset completes and also the status. It is also in hisi_hba.wq to do reset work. As all host reset works are done in hisi_hba.wq, we don't worry multiple calls to hisi_sas_controller_reset().

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.
