You can do the oprofile yourself if you don't believe me. And where else should it come from other than from mapping shared libraries ? This includes X server startup, but at least my X has a much shorter /proc/*/maps than a KDE program, so I don't think X is a significant consumer of vmas. -Andi - 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/
