	* netfs.h (netfs_report_access): Return error_t.
	* file-check-access.c (netfs_S_file_check_access): Deal with
	errors from netfs_report_access.

Sat Nov 16 17:17:50 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* io-restrict-auth.c (netfs_S_io_restrict_auth): Fix several typos.

	* fsys-getroot.c (netfs_S_fsys_getroot): iohelp_make_iouser ->
	iohelp_create_iouser.  New arg syntax for fshelp_fetch_root.

Fri Nov 15 13:39:03 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* netfs.h (struct protid): Replace member `credential' with `user'
	of new type.  All uses of old `credential' member changed to
	use `user' member.
	Change all functions that used to take `struct netcred' args to
	take `struct iouser' args.  All callers changed.
	(netfs_copy_credential, netfs_dropy_credential,
 	netfs_make_credential): Delete functions.
	* dir-lookup.c (netfs_S_dir_lookup): netfs_copy_credential ->
	iohelp_dup_iouser.
	* dir-mkfile.c (netfs_S_dir_mkfile): Likewise.
	* file-exec.c (netfs_S_file_exec): Likewise.
	* io-duplicate.c (netfs_S_io_duplicate): Likewise.
	* release-protid.c (netfs_release_protid): netfs_drop_credential
	-> iohelp_free_iouser.
	* dir-lookup.c (netfs_S_dir_lookup): Omit uses of
	netfs_interpret_credential; do it with new structures.
	* file-exec.c (netfs_S_file_exec): Likewise.
	* file-getcontrol.c (netfs_S_file_getcontrol): Likewise.
	* file-set-translator.c (netfs_S_file_set_translator): Likewise;
	using fshelp_isowner for permission check.
	* io-restrict-auth.c (netfs_S_io_restrict_auth): Likewise; guts
	rewritten.
	* dir-lookup.c (netfs_S_dir_lookup): netfs_make_credential ->
	iohelp_make_iouser.
	* fsys-getroot.c (netfs_S_fsys_getroot): Likewise.
	* fsys-syncfs.c (netfs_S_fsys_syncfs): Likewise.
	* io-reauthenticate.c (netfs_S_io_reauthenticate): Use
	iohelp_reauth instead of doing it by hand.
