I don't know why it would have been removed.  I find the sd_iostats very useful.

It provides stats for any "sd" disk.  So if you are using SCSI or SAS, and SATA in scsi-emulation mode (ie: no if you get IDE's /dev/hd*, but yes if you get /dev/sd*)

I found that it has been removed as part of “b=23988 Remove sd iostats patch from sles11 patch series”.

I’m using this patch series to patch kernel in Fedora12. Should I avoid applying this patch
when building the patched kernel?

Does this patch apply to SCSI disks only or does it apply to other type of disks (SAS/SATA) too?
