31 * This structure defines the 9p private data associated with
32 * a particular dentry. In particular, this private data is used
33 * to lookup which 9P FID handle should be used for a particular VFS
34 * operation. FID handles are associated with dentries instead of
35 * inodes in order to more closely map functionality to the Plan 9
36 * expected behavior for FID reclaimation and tracking.
