- *
- * Description:
- * The export_operations structure provides a means for nfsd to communicate
- * with a particular exported file system - particularly enabling nfsd and
- * the filesystem to co-operate when dealing with file handles.
- *
- * export_operations contains two basic operation for dealing with file
- * handles, decode_fh() and encode_fh(), and allows for some other
- * operations to be defined which standard helper routines use to get
- * specific information from the filesystem.
- *
- * nfsd encodes information use to determine which filesystem a filehandle
- * applies to in the initial part of the file handle. 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. To allow for this, it passes the
- * function acceptable() together with a @context which can be used to see
- * if the dentry is acceptable. As there can be multiple dentrys for a
- * given file, the filesystem should check each one for acceptability before
- * looking for the next. As soon as an acceptable one is found, it should
- * be returned.
- *
- * decode_fh:
- * @decode_fh is given a &struct super_block (@sb), a file handle fragment
- * (@fh, @fh_len) and an acceptability testing function (@acceptable,
- * @context). 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 it cannot, it should return a %NULL pointer if
- * the file was found but no acceptable &dentries were available, or a
- * %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or
- * %ENOMEM).
