exportfs: update documentation
Update documentation to the current state of affairs. Remove duplicated method descruptions in exportfs.h and point to Documentation/filesystems/ Exporting instead. Add a little file header comment in expfs.c describing what's going on and mentioning Neils and my copyright [1]. Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Neil Brown <neilb@suse.de> Cc: "J.

- * 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.
+ * See Documentation/filesystems/Exporting for details on how to use
+ * this interface correctly.
