blktrace was integrated into the mainline kernel between 2.6.16 and 2.6.17-rc1.
The target trace needs to run on a kernel at least that new.

If you don't have git, you can get hourly snapshots from:
excessively long mirror times, so if you have git installed, you can pull
the master tree from:
-git://git.kernel.dk/data/git/blktrace.git
+git://git.kernel.dk/blktrace.git
For browsing the repo over http and viewing history etc, you can direct
your browser to:

+A blktrace visualization tool, iowatcher, was added to blktrace in version
+1.1.0. It requires librsvg and either png2theora or ffmpeg to generate movies.
