	(diskfs_new_hardrefs, diskfs_lost_hardrefs): New declarations.
	(diskfs_nref): Call diskfs_new_hardrefs when appropriate.
	(diskfs_nput, diskfs_nrele): Call diskfs_lost_hardrefs when
	appropriate.

	* node-make.c (diskfs_make_node): Initialize NP->light_references.
	Doc fix.

Wed Jun  1 18:24:11 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)

	* dir-pathtrans.c (diskfs_S_dir_pathtrans): Skip over multiple
	slashes in pathnames by incrementing NEXTNAME after setting it.
	Also, if after we do this we discover that there is no last
	component, then set LASTCOMP and clear NEXTNAME and CREATE
	entirely, and set (new variable) MUSTBEDIR.  Then check for
	MUSTBEDIR after the node has been fetched.  Make var TYPE
	function-global and set it always, not just when NEWNODE is unset.

Fri May 27 08:47:46 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* boot-start.c (diskfs_S_exec_exec, diskfs_S_exec_setexecdata):
	Add missing args.
	(diskfs_S_exec_startup): Don't point *ARGVP to EXEC_DATA local
	storage.  Instead, copy EXEC_DATA to *ARGVP if *ARGVLEN allows;
	otherwise vm_allocate new space and copy into there.

Thu May 26 15:33:57 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)

	* diskfs.h (diskfs_nrele): Acquire lock if we are releasing
	the last reference.

	* node-drop.c (diskfs_drop_node): If we are truncating, then
	go back to normal user state and do the truncate; the next
	time through we will do the dealloc for real.
	Semantics change: now this routine is responsible for
	unlocking diskfs_node_refcnt_lock.  All callers changed.

Wed May 25 20:34:17 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* io-write.c (diskfs_S_io_write): Don't check for *AMT < 0; AMT is
	an out-only parameter.

	* ports-consts.c (ports_use_multiple_threads): Deleted definition.

	ports_manage_port_operations_multithread instead of
	ports_maange_port_operations.
	* init-loop.c (diskfs_main_request_loop): Likewise.

	* dir-pathtrans.c (diskfs_S_dir_pathtrans): Reference node in
	lookup of empty path case so that common code at the out: label
	doesn't free an extra one.

Mon May 23 23:13:51 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)

	* boot-start.c (diskfs_S_fsys_init): Start exec_init after
	proc_child.

	node after calling diskfs_finish_protid.

Thu May 12 14:23:29 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	* Makefile (clean): Add fsys_reply.h and *User.c.

Thu May 12 03:45:38 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* Makefile (fsys_reply.h fsys_replyUser.c): New rule.
	(MIGSTUBS): Add fsys_replyUser.o.
	* boot-start.c: Include fsys_reply.h.
	(diskfs_S_fsys_init): Take new reply port args.
	Send reply msg as soon as verified, before doing anything.

Mon May  9 16:58:24 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	* diskfs.h (diskfs_init_completed): New function declaration.
	* boot-start.c (diskfs_S_fsys_init): Don't call _hurd_proc_init.
	Do call diskfs_init_completed.

Thu May  5 13:04:43 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	* dir-pathtrans.c (diskfs_S_dir_pathtrans): Behave properly
	if nextname is null.  Copy nextname to the end of the symlink
	target rather than vice versa.  Don't punt to the caller before
	doing the append.
	(diskfs_S_dir_pathtrans): O_NOTRANS should prevent symlink
	interpretation.
	(diskfs_S_dir_pathtrans): If a symlink traversal was the last
	component, then clear CREATE (symlinks to nothing don't honor
	O_CREAT) and clear LASTCOMP (because it isn't true any longer).

	* dir-pathtrans.c (diskfs_S_dir_pathtrans): Fix mangled check
	for O_NOLINK.
	(diskfs_S_dir_pathtrans): Repair furtherly mangled check for
	O_NOLINK.

	* conch-set.c (ioserver_put_shared_data): Set
	optimal_transfer_size from the same thing we return in stat.

	* io-async.c (diskfs_S_io_async): Just return EOPNOTSUPP without
	doing anything more at all.

Thu May  5 06:32:10 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	type vm_offset_t.

	* io-map-cntl.c (diskfs_S_io_map_cntl): Take 3rd result arg
	for msg type of *CTLOBJ; set it to copy-send.

	* io-async.c (diskfs_S_io_async): Take 3rd result arg for msg type
	of *IDPORT; set it to copy-send.  Return 0 instead of EOPNOTSUPP;
	should not be deallocating NOTIFY if returning an error.

	* io-async-icky.c (diskfs_S_io_get_icky_async_id): Take 3rd result arg
	for msg type of *IDPORT; set it to copy-send.

	* conch-set.c (ioserver_put_shared_data): Temporarily #if 0
	setting of optimal_transfer_size from bogus undeclared variable.

	* protid-make.c: Include <string.h> to get bcopy declared.

	* {file,dir,io,fsys}-*.c: Changed return type of all RPC server
	functions to kern_return_t.  error_t is not compatible with the
	declarations in the mig-generated header files.

	* Makefile: Change uses of $(headers) to $(includedir).

	* file-exec.c (diskfs_S_file_exec): Fix msg type arg in exec_exec call.

	* dir-pathtrans.c (diskfs_S_dir_pathtrans): Add missing close paren.

	* boot-start.c (diskfs_start_bootstrap): Pass msg type arg for
	FILE arg to exec_exec.
	(diskfs_S_fsys_getpriv): Change return type to kern_return_t.
	error_t is not compatible with the declarations in the
	mig-generated header files.
	(diskfs_S_fsys_init): Likewise.
	(exec_stack_base, exec_stack_size): New variables.
	(diskfs_S_exec_startup): Use those for stack values in reply.
	(start_execserver): Pass them to mach_setup_thread to be initialized.

Mon May  2 16:32:22 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	* dir-pathtrans.c: Test for O_NOLINK flag was mangled.

Fri Apr 29 16:44:08 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)

	* io-stubs.c (diskfs_S_io_readnotify): New function.

	* conch-set.c (ioserver_put_shared_data): Set new fields
	optimal_transfer_size (to sblock->fs_bsize) and
	use_readnotify_size (to zero).

	* file-exec.c (diskfs_S_file_exec): Change call to exec_exec in
	accord with interface change in exec.defs.

Mon Feb 14 11:26:26 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* boot-start.c: #include <hurd.h>.
