Moved the READ and WRITE switch cases to the top. Added a default case to the switch case and replaced duplicate scsi result value with a macro. The idea is that since most of scsi commands we care about performance wise are read or write, we need to process them first. Internally the compiler (GCC) converts a switch case into either a jump table or a bunch of if else conditions, so placing the often used read, write cases at the top is an effort in optimization.

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.
