only take the bare essentials, which currently means removing "maxreqlen" from the argument list (all current callers I'm aware of set it as 0 anyway). Introduce puffs_init(), which provides a context for setting various parameters and puffs_domount(), which can be used to mount the file system. Keep puffs_mount() as a shortcut for the above two for simple file systems. Bump development ABI version to 13. After all, it's Friday the 13th. Watch out! Bad things can happen on Friday the 13th. --No carrier--
