Description: I request enabling the CONFIG_BLK_DEV_IO_TRACE in Arch Linux's kernel configuration, used by the blktrace utility. blktrace is a block-layer I/O tracing mechanism.

blktrace is mainly useful for server administrators and software developers for optimizing their I/O performance.
It's also useful for laptop users to find out which process keeps spinning up the hard drive and wasting power!

The user space utilities are available on AUR: http://aur.archlinux.org/packages.php?ID=31371

This is the only reason why I'm currently building my own kernel.

Other distros including Debian [1], Ubuntu and OpenSUSE [2] enable this option by default.
