Hi all!

I just ran the tests and obtained this:

I have to say that I killed the dd program manually because it took to much time. 

I don't know if it's an issue to get about 1,2MB/S IO as much... I suppose that even for a laptop this is not much normal.


Anyway there are results. 
I updated testsuite to include this new test.

It's called kernel-testsuite.tar.gz and it includes:
   kernel-test-fsync.sh
   fsync-tester

The package contains Theodore Ts'o sources but modified to use 1 parameter for the filename of the output.


I hope this helps.
