Pawel Jakub Dawidek 1a60c7fc8e Add gjournal specific code to the UFS file system: ... - Add FS_GJOURNAL flag which enables gjournal support on a file system. - Add cg_unrefs field to the cylinder group structure which holds number of unreferenced (orphaned) inodes in the given cylinder group. - Add fs_unrefs field to the super block structure which holds total number of unreferenced (orphaned) inodes. - When file or a directory is orphaned (last reference is removed, but object is still open), increase fs_unrefs and cg_unrefs fields, which is a hint for fsck in which cylinder groups looks for such (orphaned) objects. - When file is last closed, decrease {fs,cg}_unrefs fields. - Add VV_DELETED vnode flag which points at orphaned objects.
