You'd first have to find the highest number currently assigned and then add a bit of safety margin to decide on a starting point for the new numbers. Should architecture dependent system calls be assigned from a separate interval where they could overlap between architectures? Or should they be assigned from the same sequence as other calls and return -ENOSYS on other architectures than the one they were targeted for? Or was it all a joke, and you don't actually want that cleanup to happen because of too much breakage? -- Kasper Dupont -- Rigtige m?nd skriver deres egne backupprogrammer #define _(_)"d.%.4s%."_"2s" /* This is my email address */ char*_="@2kaspner"_()"%03"_("4s%.")"t\n";printf(_+11,_+6,_,11,_+2,_+7,_+6); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
