+ * struct export_operations - for nfsd to communicate with file systems
+ * @decode_fh: decode a file handle fragment and return a &struct dentry
+ * @encode_fh: encode a file handle fragment from a dentry
+ * @get_name: find the name for a given inode in a given directory
+ * @get_parent: find the parent of a given directory
+ * @get_dentry: find a dentry for the inode given a file handle sub-fragment
+ * @find_exported_dentry:
+ * set by the exporting module to a standard helper function.
+ *
+ * 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).
+ *
+ * encode_fh:
+ * @encode_fh should store in the file handle fragment @fh (using at most
+ * @max_len bytes) information that can be used by @decode_fh to recover the
+ * file refered to by the &struct dentry @de. 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. The name should be stored in the @name (with the
+ * understanding that it is already pointing to a a %NAME_MAX+1 sized
+ * buffer. get_name() should return %0 on success, a negative error code
+ * or error. @get_name will be called without @parent->i_mutex held.
+ *
+ * get_parent:
+ * @get_parent should find the parent directory for the given @child which
+ * is also a directory. In the event that it cannot be found, or storage
+ * space cannot be allocated, a %ERR_PTR should be returned.
+ *
+ * get_dentry:
+ * Given a &super_block (@sb) and a pointer to a file-system specific inode
+ * identifier, possibly an inode number, (@inump) get_dentry() should find
+ * the identified inode and return a dentry for that inode. Any suitable
+ * dentry can be returned including, if necessary, a new dentry created with
+ * d_alloc_root. The caller can then find any other extant dentrys by
+ * following the d_alias links. If a new dentry was created using
+ * d_alloc_root, DCACHE_NFSD_DISCONNECTED should be set, and the dentry
+ * should be d_rehash()ed.
+ *
+ * If the inode cannot be found, either a %NULL pointer or an %ERR_PTR code
+ * can be returned. The @inump will be whatever was passed to
+ * nfsd_find_fh_dentry() in either the @obj or @parent parameters.
+ *
+ * Locking rules:
+ * get_parent is called with child->d_inode->i_mutex down
+ * get_name is not (which is possibly inconsistent)
