Modified files:
sys/sys vnode.h
sys/kern vfs_subr.c
sys/ufs/ffs ffs_extern.h ffs_vfsops.c fs.h
sys/ufs/ufs ufs_inode.c ufs_vnops.c
Added files:
sys/ufs/ufs gjournal.h ufs_gjournal.c
Log:
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.
