Hork...
Identify the generic ioctls that are relevant to a FUSE file system and have real meaning *and* are useful. Teach fuse to turn those to and from messages properly and if you must add any others (ie if there is good reason to want them then add a single FUSEFS ioctl something like
struct fusefs_ioctl { u32 opcode; void *data_in; void *data_out; u16 size_in; u16 size_out; }
so that anything totally weird can be passed through without horrible /proc/... hacks and without putting tons of cases into FUSE
