Dear Mark,
I appreciate the OSDL efforts and graphs you offer for ReiserFS 4, but I will appreciate a lot more if you adopt a distro that adopt ReiserFS like: SuSE, Lindows or our FTOSX.
For us ReiserFS is important for RedHat really don't.
So, I don't want to see again the RedHat 9, name here: http://developer.osdl.org/markw/fs/dbt2_stp_results.html
Thanks very much, Giovanni
