Bug#433204: Add task I/O accountiong



Package: linux-2.6
Severity: wishlist

--- Please enter the report below this line. ---

With these config parameters, we can view which process are responsible of 
disk activity.

CONFIG_TASKSTATS=y
CONFIG_TASK_DELAY_ACCT=y
CONFIG_TASK_XACCT=y
CONFIG_TASK_IO_ACCOUNTING=y

This is directly handled by pidstat -d of the sysstat package and atop.

I don't know if there is performance impacts with these parameters, anyway I 
wish their activation will be discussed.
