I am preparing now two kernels against Linux v3.8-rc3 (as your patchset applies cleany) with 2 important patches which I need here (1. mei: no proper reboot and 2. (S)ATA fix).
I will attach two tarballs for each kernel-setup and run LTP "lite" again (tarballs will include the results).

Hmm, regressions is always good to test. As a "customer" aka tester I want to see any benefit means for most power-users: Do I get some speedups? That's the main background of my askings.
As said here I am running Ubuntu as a WUBI-installation. This system is predestinated for testing loop improvements. So again and no sorry: How can I test reliable speed improvements? I remember linux-fs/linux-xfs folks have a tool could be named "xfstests" (note2myself: more coffee!). Any hints for testing appreciated!
