Iotop Not Enabled in Kernel, Can It Be Enabled?

[Akuma]

In order to preserve the sdcard, I wanted to take a look at the disk IO with "iotop".
Unfortunately it comes back with this error:

CONFIG_TASK_DELAY_ACCT not enabled in kernel, cannot determine SWAPIN and IO %

If its not too much trouble, can it be enabled ?

Delay accounting is not cheap, which is the main reason why it was disabled in the kernel I assume.

Then please don't
