The older RHEL kernels had some cases that didn't quite account exactly but current ones ought to be right - for Centos I'd expect similar but ask there not here as it is a very old and branched away kernel. > It allocates memory of different sizes (not that it matters much due > to caching of diffeent malloc.

The real test is whether the values go back properly when you kill the program. - 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/
