I have used it because this is reasonably fast to compile. I don't think there is a best single .config for testing ext4 (but let's see what other think). Using .config from distributions is fine since it is the way some users get ext4 (that's why I tested Fedora 9 too). Using other ways is also fine since it increases testing coverage. > Are there any settings > that should be added/delete/modified from the default? Yes, for example, defconfig lacks options from the "Kernel Hacking" section for testability which are mentionned e.g. in Documentation/SubmitChecklist. -- solofo
