find_raid56_stripe_len statically returns SZ_64K which equals BTRFS_STRIPE_LEN. It's sole caller is __btrfs_alloc_chunk and it assigns the return value to ai variable which is already set to BTRFS_STRIPE_LEN. So remove the function invocation altogether and remove the function itself. Also remove the variable since it's only aliasing BTRFS_STRIPE_LEN and use the define directly. Use the occassion to simplify the rounding down of stripe_size now that the value we want it to align is a power of 2.

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.
