- * nfsInit() issues a warning if you run a version with 'short st_ino'.]
- *
- * As a workarount, we merge the upper 16bits of the fileid into the
- * minor device no. Hence, it is still possible to uniquely identify
- * a file by looking at its device number (major = nfs, minor = part
- * of the fileid + our 'nfs-id' identifier).
- *
- * This has an impact on performance, as e.g. getcwd() stats() all
- * directory entries when it believes it has crossed a mount point
- * (a.st_dev != b.st_dev).
- *
- * OTOH, it also might cause node comparison failure! E.g. 'getcwd()'
- * assumes that two nodes residing in the same directory must be located
- * on the same device and hence compares 'st_ino' only.
- * If two files in the same directory have the same inode number
- * modulo 2^16, they will be considered equal (although their device
- * number doesn't match - getcwd doesn't look at it).
- *
- * Other software might or might not be affected.
- *
- * The only clean solution to this problem is bumping up the size of
- * 'ino_t' at least to 'long'.
- * Note that this requires _all_ software (libraries etc.) to be
- * recompiled.

-	File Handlers
-
-	NOTE: the FS generics expect a FS'
-	      evalpath_h() to switch the
-		  pathloc->handlers according
-		  to the pathloc/node's file
-		  type.
-		  We currently have 'file' and
-		  'directory' handlers and very
-		  few 'symlink' handlers.
-
-		  The handlers for each type are
-		  implemented or #defined ZERO
-		  in a 'nfs_file_xxx',
-		  'nfs_dir_xxx', 'nfs_link_xxx'
-		  sequence below this point.
-
-		  In some cases, a common handler,
-		  can be used for all file types.
-		  It is then simply called
-		  'nfs_xxx'.
