Lines Matching full:directory

154 /* Every directory can have many redundant directory entries scattered
155  * throughout the directory tree.  First there is the directory entry
156  * with the name of the directory stored in the parent directory.
157  * Then, there is the "." directory entry stored in the directory
158  * itself.  Finally, there are possibly many ".." directory entries
164  * the many redundant entries for each directory.  We normalize the
165  * block and offset by always making them point to the "."  directory.
167  * Notice that we do not use the entry for the directory with the name
168  * that is located in the parent directory.  Even though choosing this
169  * first directory is more natural, it is much easier to find the "."
172  * redundant entries for the directory.  Thus, it can always be
173  * reached regardless of which directory entry you have in hand.
175  * This works because the "." entry is simply the first directory
176  * record when you start reading the file that holds all the directory
181  * You should pass the directory entry in "de".  On return, "block"
183  * affected making it safe to call even for non-directory file
