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.

Just git clone the repo:


git://git.kernel.dk/blktrace.git


(which is mentioned in the Kconfig help entry for that kernel config

option)


or grab the latest snapshot here:


http://brick.kernel.dk/snaps/blktrace-git-latest.tar.gz


it comes with documentation and man pages (mostly thanks to others than

myself :-) and also a nifty btt tool that can do lots of things that

blkparse cannot.

or http://www.kernel.org/pub/linux/kernel/people/axboe/tools/blktrace.c
