do you know if there's such a patch for linux kernel 2.4.6, since it seems
the structures are changed and the sard patch versions I can find are not
compatible to this kernel.
thanks in advance, gilly

thanks, it looks like you are correct and I have applied your patch. Most
of the machines around here have the "sard" patch applied (which gives
extra I/O accounting in /proc/partitions) and if sard stats are available
then /proc/stat is not used for disk stats.
