Introduce a new header, kernel-lib/raid56.h, for later raid56 works. It contains 2 functions, from original btrfs-progs code: void raid6_gen_syndrome(int disks, size_t bytes, void **ptrs); int raid5_gen_result(int nr_devs, size_t stripe_len, int dest, void **data); Will be expanded later and some part of it(RAID6 recover part) may keep sync with kernel later.
