- * XFS encodes and decodes the fileid portion of NFS filehandles
- * itself instead of letting the generic NFS code do it.  This
- * allows filesystems with 64 bit inode numbers to be exported.
- *
- * Note that a side effect is that xfs_vget() won't be passed a
- * zero inode/generation pair under normal circumstances.  As
- * however a malicious client could send us such data, the check
- * remains in that code.
+ * Note that we only accept fileids which are long enough rather than allow
+ * the parent generation number to default to zero.  XFS considers zero a
+ * valid generation number not an invalid/wildcard value.
