97*7c478bd9Sstevel@tonic-gate  * The vnode is the focus of all file activity in UNIX.
98*7c478bd9Sstevel@tonic-gate  * A vnode is allocated for each active file, each current
99*7c478bd9Sstevel@tonic-gate  * directory, each mounted-on file, and the root.
100*7c478bd9Sstevel@tonic-gate  *
101*7c478bd9Sstevel@tonic-gate  * Each vnode is usually associated with a file-system-specific node (for
102*7c478bd9Sstevel@tonic-gate  * UFS, this is the in-memory inode).  Generally, a vnode and an fs-node
103*7c478bd9Sstevel@tonic-gate  * should be created and destroyed together as a pair.
104*7c478bd9Sstevel@tonic-gate  *
105*7c478bd9Sstevel@tonic-gate  * If a vnode is reused for a new file, it should be reinitialized by calling
106*7c478bd9Sstevel@tonic-gate  * either vn_reinit() or vn_recycle().
107*7c478bd9Sstevel@tonic-gate  *
108*7c478bd9Sstevel@tonic-gate  * vn_reinit() resets the entire vnode as if it was returned by vn_alloc().
109*7c478bd9Sstevel@tonic-gate  * The caller is responsible for setting up the entire vnode after calling
110*7c478bd9Sstevel@tonic-gate  * vn_reinit().  This is important when using kmem caching where the vnode is
111*7c478bd9Sstevel@tonic-gate  * allocated by a constructor, for instance.
112*7c478bd9Sstevel@tonic-gate  *
113*7c478bd9Sstevel@tonic-gate  * vn_recycle() is used when the file system keeps some state around in both
114*7c478bd9Sstevel@tonic-gate  * the vnode and the associated FS-node.  In UFS, for example, the inode of
115*7c478bd9Sstevel@tonic-gate  * a deleted file can be reused immediately.  The v_data, v_vfsp, v_op, etc.
116*7c478bd9Sstevel@tonic-gate  * remains the same but certain fields related to the previous instance need
117*7c478bd9Sstevel@tonic-gate  * to be reset.  In particular:
