Our improvements works of unionfs are going step by step. p19 is milestone release. Patchset-19-20070504: For 7-current http://people.freebsd.org/~daichi/unionfs/unionfs-p19-20070504.diff For 6-stable http://people.freebsd.org/~daichi/unionfs/unionfs6-p19-20070504.diff Changes in unionfs-p19-20070504.diff - It has been became MPSAFE. - Default copy mode has been changed from traditional-mode to transparent-mode. Some folks who have reported some issues have solved with transparent mode. We guess it is time to change the default copy mode. The transparent-mode is the best in most situations. - Fixed kern/111262 issue. - Added support of vfs_cache on unionfs. As a result, you can use applications that use procfs on unionfs. - Removed unionfs internal cache mechanism because it has vfs_cache support instead. As a result, it just simplified code of unionfs. - Added whiteout behavior option. ``-o whiteout=always'' is default mode(it is established practice) and ``-o whiteout=whenneeded'' is less disk-space using mode especially for resource restricted environments like embedded environments. (Contributed by Ed Schouten. Thanks) - Fixed a mtx lock issue happened with nullfs. - Fixed lock issues around unionfs. - Added NULL check code pointed out by Coverity. (Pointed out by Stanislav Sedov. Thanks) The documents of those unionfs patches: http://people.freebsd.org/~daichi/unionfs/ (English) http://people.freebsd.org/~daichi/unionfs/index-ja.html (Japanese) Request for Test: Unionfs lovers including FreeSBIE developers, ports cluster managers, heavy memory-fs users and folks use unionfs, could you try p19 please? Merge plan: I have plan to commit unionfs-p19-20070504.diff to -current after received unionfs users responses. Thanks P.S. I am going to join BSDCan 2007. Lets meet at Ottawa, Canada :) -- Daichi GOTO, http://people.freebsd.org/~daichi
