nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except that the first pointer is 'struct readdir_cd *' rather than 'void *'. It then casts encode_dent_fn points to 'filldir_t' as needed. This hides any other type mismatches between the two such as the fact that the 'ino' arg recently changed from ino_t to u64. So: get rid of 'encode_dent_fn', get rid of the cast of the function type, change the first arg of various functions from 'struct readdir_cd *' to 'void *', and live with the fact that we have a little less type checking on the calling of these functions now. Less internal (to nfsd) checking offset by more external checking, which is more important. Thanks to Gabriel Paubert <paubert@iram.es> for discovering this and providing an initial patch.
