Function __get_raid_index() is used to convert block group flags into raid index, which can be used to get various info directly from btrfs_raid_array[]. Refactor this function a little: 1) Rename to btrfs_bg_flags_to_raid_index() Double underline prefix is normally for internal functions, while the function is used by both extent-tree and volumes. Although the name is a little longer, but it should explain its usage quite well. 2) Move it to volumes.h and make it static inline Just several if-else branches, really no need to define it as a normal function. This also makes later code re-use between kernel and btrfs-progs easier. 3) Remove function get_block_group_index() Really no need to do such a simple thing as an exported function.

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.
