- * Hence we return a "magic" fid for all but /afs. If it goes through the
- * translator code, it will get transformed into a SmallFid that we recognize.
- * So, if submounts are disallowed, and an NFS client tries a submount, it will
- * get a fid which we don't recognize and the mount will either fail or we
- * will ignore subsequent requests for that mount.
- *
- * The Alpha fid is organized differently than for other platforms. Their
- * intention was to have the data portion of the fid aligned on a 4 byte
- * boundary. To do so, the fid is organized as:
- * u_short reserved
- * u_short len
- * char data[8]
- * The len field is the length of the entire fid, from reserved through data.
- * This length is used by fid_copy to include copying the reserved field.
- * Alpha's zero the reserved field before handing us the fid, but they use
- * it in fid_cmp. We use the reserved field to store the 16 bits of the Vnode.
- *
- * Note that the SmallFid only allows for 8 bits of the cell index and
