[ Upstream commit1c90836f70] struct ufs_dev_cmd is the main container that supports device management commands. In the case of a read descriptor request, we assume that the proper space was allocated in dev_cmd to hold the returning descriptor. This is no longer true, as there are flows that doesn't use dev_cmd for device management requests, and was wrong in the first place.

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.
