We already have define_extent() that prepares necessary data for the Define Extent CCW. The exact same thing is done in prefix_LRE(). Remove the duplicate code and move commands that were only used in combination with the Prefix command to define_extent(). One of these commands needs the blocksize to be specified. Add the blksize parameter to define_extent() to account for that. In addition, the check_XRC() function can be made more generic. Do this and remove the Prefix-specific check_XRC_on_prefix() function. Furthermore, prefix_LRE() uses fill_LRE_data() to prepare Locate Record Extended data. Rename the function to fit the scheme better and make it usable outside of the Prefix context by adding the corresponding CCW command.

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.
