Hi Folks, You may have seen my other Soft-updates journaling (SUJ) announcements. If not, it is a journaling system that works cooperatively with soft-updates to eliminate the full background filesystem check after an unclean shutdown. SUJ may be enabled with tunefs -j enable and disabled with tunefs -j disable on an unmounted filesystem. It is backwards compatible with soft-updates with no journal. I'm going to do another round of tests and buildworld this afternoon to verify the diff and then I'm committing to head. This is a very large feature and fundamentally changes softupdates. Although it has been extensively tested by many there may be unforseen problems. If you run into an issue that you think may be suj please email me directly as well as posting on current as I sometimes miss list email and this will ensure the quickest response. Thanks, Jeff
