A header file for both of kernelspace and userspace. For the new file fs/aufs/Kconfig, the maximum number of branches is customizable, and it determines the type (size) of 'aufs_bindex_t.' The type is always 'signed.' If we made it 'unsigned,' then more branches would be available. But generally I think 127 (default) is enough and it won't be a big issue. For those who wants more than 127 branches, other values are available. But we should care the size of the internal pointer arrays, and it is good for the performance to keep it in a page at most. AUFS_BRANCH_MAX_511 is mainly for 64bit systems which limits the internal array size less than 4k (511 x 8bytes < 4k). Similarly for 32bit systems, AUFS_BRANCH_MAX_1023 (1023 x 4 bytes < 4k).
