	* node.c (diskfs_free_node): Reset hnext's hprevp.
	(diskfs_node_norefs): Likewise.
	(diskfs_cached_lookup): Fix insane code for finding existing node ptr.
	(diskfs_get_filemap_pager_struct): Remove spurious assert.
	(diskfs_get_filemap): Always add a reference to the send right.

	* dir.c (diskfs_get_directs): When using st_size, calculate additional
	space for . and .. entries.  Skip . and .. entries when ENTRY says to.
	Set d_fileno=2 for .. entry when it is the parent of the filesystem.

	* tmpfs.c (main): Don't lock diskfs_root_node after alloc,
	which already locks it.  In root node's mode, clear S_ITRANS bits
	and set S_IROOT bit.

2001-02-25  Roland McGrath  <roland@frob.com>

	* pager-stubs.c: New file.
	* Makefile (SRCS): Add it.

	* node.c (diskfs_S_file_get_storage_info): New function.
	* tmpfs.c (diskfs_synchronous): New variable.

	* dir.c (diskfs_lookup_hard): Look up .. disknode's in-core node.

	* node.c: #include <mach/default_pager.h>.

2000-12-30  Marcus Brinkmann  <marcus@gnu.org>

	* dir.c: Include <stddef.h>, <unistd.h>, <sys/mman.h>
	(diskfs_get_directs): Cast *data to struct dirent *.

	* node.c: Include <stddef.h>.
	(diskfs_alloc_node): Remove unused variables err, st, np.
	(diskfs_free_node): Use *np->dn, not *dn to calculate used space.
	(recompute_blocks): Replace DT_DEV with DT_BLK.
	(diskfs_node_norefs): Likewise.
	(recompute_blocks): Take address of np->dn_stat for pointer st.
	(diskfs_cached_lookup): New variable st.
	(diskfs_cached_lookup): Set st to &np->dn_stat, not &dn->dn_stat.
	(create_symlink_hook): Fix malloc call and return code check.
	(read_symlink_hook): Return 0.

	* tmpfs.c: Include <argp.h>, <string.h>, <inttypes.h>, <argz.h>,
	<error.h>.
	(parse_opt): Reverse second and third argument of strtoimax call.

	* tmpfs.h (struct disknode): Remove blind passenger (unnamed copy
	of anonymous struct {} reg).

	Some of the above were also reported by Alexey Dejneka
	<adejneka@comail.ru>.

2000-12-28  Roland McGrath  <roland@frob.com>

	* node.c (recompute_blocks): New function, broken out of ...
	(diskfs_cached_lookup): here.  Now use call that.
	(diskfs_set_translator): Likewise.
	(create_symlink_hook): Likewise.  Do nothing for zero-length target.

	* Makefile, tmpfs.c, tmpfs.h, node.c, dir.c: New files.
