Yes, __LTP__NR_INVALID_SYSCALL is better than -1 (for all archs we have
#define __LTP__NR_INVALID_SYSCALL -1)

But I'd also use __NR_syscalls from <asm-generic/unistd.h> (the second suggested
case), i.e. have arch dependent value based on UAPI headers.

Also, you could add a real description to the values to .desc.

Kind regards,
Petr
