[Bug 157191] please enable CONFIG_TASKSTATS, especially CONFIG_TASK_IO_ACCOUNTING

[Pasi Savolainen]

Public bug reported:

Linux kernel has very useful task IO information (reflected into /proc/self/io and other places) similar to what 'vmstat' gives.
It needs that in kernel configuration CONFIG_TASKSTATS and CONFIG_TASK_IO_ACCOUNTING are enabled.
In current gutsy (2.6.22.14.21) kernel they are not enabled.

There is also very handy 'iotop.py' program available at
