[Bug 157191] Re: please enable CONFIG_TASKSTATS, especially CONFIG_TASK_IO_ACCOUNTING

[gmayer]

I need to second this request. Being able to view disk i/o stats per
process is very important as it would greatly help newbies, advanced
users and developers alike to track down what i/o hogging processes are
causing their ubuntu systems to slow down. This happens more than people
think, the recent spate of bugs/forum posts related to trackerd is just
one example of how top/vmstat/iostat et al are useless for such a task.

People are asking for this capability all the time, see

as just some examples of users screaming for this functionality. While
I'm an avid Ubuntu user myself (I completely wiped my M$ Windoze
partition btw) I think it's pretty sad that all other OS's have that
capability built-in but ubuntu doesn't, and all it takes to fix is to
turn on a simple kernel config option...

BTW, I got alerted to this by an excellent thread on linuxquestions

http://www.linuxquestions.org/questions/linux-kernel-70/how-to-enable-
process-io-statistics-600777/#post2963872

which mentions that the latest version of collectl also supporting the
"new" i/o /proc interface (not in the repos yet, see bug# 135037)
