diskio patch is a kernel patch.

The 2.4.X kernel doesn't report disk IO in /proc/stat for any devices over either major 16 or minor 16. This inclues /dev/hdb and /dev/hdd. This patch changes the system from using a memory wasting array to a more intelligent list system. It is marginally more expensive in overhead processing for each disk IO.

PRO: Less memory required, faster /proc/stat, all block devices recorded.
CON: Timing critical section? Negligible for desktop user, and minimal impact for a server with umpteen SCSI arrays.

Since version 2.4.20 the kernel can now optionally report disk statistics in /proc/partitions for all drives and each individual partition. I'll still be keeping this patch upto date as I use it for GKrellM and for any other programs that use /proc/stat. To its advantage, reading /proc/stat uses much less overhead than reading /proc/partitions ten times a second.

What's New in This Release:
The patch-diskio-2.4.27-1 file patches kernels 2.4.19 to 2.4.27
