The + * standard helper routines assume that this fragment will contain one or + * two sub-fragments, one which identifies the file, and one which may be + * used to identify the (a) directory containing the file. + * + * In some situations, nfsd needs to get a dentry which is connected into a + * specific part of the file tree.

The remainder, termed - * a file handle fragment, is controlled completely by the filesystem. The - * standard helper routines assume that this fragment will contain one or - * two sub-fragments, one which identifies the file, and one which may be - * used to identify the (a) directory containing the file. - * - * In some situations, nfsd needs to get a dentry which is connected into a - * specific part of the file tree.

It should return a &struct dentry which refers to the same - * file that the file handle fragment refers to, and which passes the - * acceptability test.

If the @connectable flag is - * set, the encode_fh() should store sufficient information so that a good - * attempt can be made to find not only the file but also it's place in the - * filesystem. This typically means storing a reference to de->d_parent in - * the filehandle fragment. encode_fh() should return the number of bytes - * stored or a negative error code such as %-ENOSPC - * - * get_name: - * @get_name should find a name for the given @child in the given @parent - * directory.
