But there might be 32-bit applications out there which are using the present wrong structure? otoh, I assume that those applications would be using taskstats.h and would hence encounter this bug and we would have heard about it, is that correct? otoh^2, 32-bit applications running under 32-bit kernels will presently be functioning correctly, and your change will require that those applications be recompiled, I think? This patch looks like 2.6.20 and 2.6.21 material, but very carefully... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
