Good idea. But have you tried to look at slabinfo? Try to run slabinfo -t which will calculate the allocation overhead of the currently allocated objects in all slab caches. One problem: The actual size of kmalloc'ed objects is not available so it does not calculate the overhead that comes about because of rounding. Your approach would cover that as well but I think we could also add a debug mode in which we store the actual size of a kmalloc object and export the information via sysfs. Would be nicer than adding this whole additional layer. -- 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/
