FS#3102 - storage I/O accounting impeded by unset kconf

userland *htop* or *pidstat* require the necessary kconf set http://sebastien.godard.pagesperso-orange.fr/tutorial.html

With its -d option, pidstat can report I/O statistics, providing that you have a recent Linux kernel (2.6.20+) with the option CONFIG_TASK_IO_ACCOUNTING compiled in.
