Re: [dm-devel] What's the status on I/O-stats for dm block devices?

Hi,

I'm running a newsserver with the newsspool on LVM2.
It's working great for years already. Thanks for the great software!

Question: Device mapper doesn't provide I/O-statistics yet.
I found a bug in de Linux kernel bug tracker about this topic,
with a patch from Kevin Corry. I added a comment to the bug report,
asking about the status of the patch, and got a reply from Jens Axboe.
He advised me to ask my question on this list.

See: http://bugme.osdl.org/show_bug.cgi?id=1806

Could anybody comment on Jens' reply, and tell me wether we can
expect a solution? I can't imagine I'm the only one needing this...

Thanks.

IIRC, there was a patch submitted recently to address this, so I'm assuming it will be released relatively soon. It looks somewhat like the patch you described above, just a little simpler. Thank you,

Josef
