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.
