Subject: blktrace debugging: how to use it

The is patch is to enable blktrace debugging in the kernel:

http://lkml.org/lkml/2006/8/1/405

Can anyone provide any guidelines or references on how to use this
feature from userspace? Any tools written to TEST and use this feature?

Thanks.

All I remember, the user space code is available from Jens Axboe's CVS
or http://www.kernel.org/pub/linux/kernel/people/axboe/tools/blktrace.c
