Any tools written to TEST and use this feature? 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. -- Jens Axboe
