Is there an easy way to define multiple new syscalls in an LKM? Using
the MOD_SYSCALL macro more than once results in errors (error:
redefinition of `_module'), and pulling MOD_SYSCALL apart and trying
to do the equivalent myself looks painful.

Alternatively, am I better off just defining a single syscall and
using a selector to choose the appropriate function, ioctl style?

Thanks,
