	Oops! The BkDat for new files and directories was in 1972 when
	it should have been in 1904 (not that it matters that much).

	* inode.c:
	The HFS MdDat should be the larger of the i_mtime and i_ctime.

	* README.sgml:

	* version.c, README.sgml:
	Bump version up to "pre-0.7-7".

	* bnode.c:

Sun Aug 18 23:16:43 1996  Paul H. Hargrove  <[e-mail]>

	* version.c, README.sgml:
	Bump version to "pre-0.7-5" for test release.

	* dir_cap.c, README.sgml:
	Change ".:rootinfo:" to ".rootinfo".

	* hfs_fs.h, dir_cap.c, dir_dbl.c, dir_nat.c:
	Mangle the names as first step in hfs_{cap,dbl,nat}_lookup().
	Use the new hfs_streq() to catch mixed case matches to the special
	files and directories in hfs_{cap,dbl,nat}_lookup().
	Store reserved names only once.

	* dir.c, hfs.h, string.c:
	Implement hfs_streq() which tests for string equality more
	rapidly than hfs_strcmp() by checking for equal length first,
	and use it when checking for reserved names.

	* inode.c, TODO, dir_cap.c, dir_dbl.c, README.sgml:
	Provide the metadata for the root directory for the CAP and AppleDouble
	schemes in the files ".:rootinfo:" and "%RootInfo", respectively.

	Add items corresponding to some of the 'XXX' comments in the sources.

	* dir_dbl.c, dir_cap.c:
	Update comments, removing ref. to a comment that once existed in inode.c

	* catalog.c:
	Remove some redundant locking and error checks
	that had been previously marked as questionable.

Sat Aug 17 08:06:56 1996  Paul H. Hargrove  <[e-mail]>

	* binsert.c, bfind.c, bins_del.c, balloc.c, bdelete.c:

	Move looping from hfs_cat_next() into hfs_bsucc(),
	where it can be done an entire node at a time.

Fri Aug 16 05:02:59 1996  Paul H. Hargrove  <[e-mail]>

	* TODO:
	Add AppleShare support to the list of goals.

	* trans.c, super.c, hfs_fs.h, README.sgml:
	Add a "names=netatalk" mount option, since
	Netatalk quotes initial periods and CAP doesn't.

	Oops! Had removed the 'include .depend' from Makefile.

	* inode.c, hfs_fs.h, file_nat.c, file_dbl.c, file.c, dir_nat.c,

	Update for 2.0.1 and newer kernels.

	* Makefile:
	Get rid of ifeq stuff and use a .tmpdepend file to make sure
	a failed 'make depend' doesn't allow a 'make hfs.o'.

Wed Aug 14 01:03:01 1996  Paul H. Hargrove  <[e-mail]>

	* version.c, README.sgml:
	Bump version up to "pre-0.7-3" in preparation for snapshot release.

	* btree.c, extent.c, bnode.c:
	Fix up some debugging code.

Tue Aug 13 12:42:12 1996  Paul H. Hargrove  <[e-mail]>

	* version.c, README.sgml:
	Bump revision to "pre-0.7-2".

	* super.c, sysdep.c, mdb.c, file_nat.c, inode.c, file_cap.c,
	  file_dbl.c, file.c, extent.c, dir.c, catalog.c, btree.c, bnode.c,
	  balloc.c:
	Added the remaining missing function comments.

	* Makefile, README.sgml:
	Simplify the default make rule to build the dependency file AND hfs.o.
	Change the installation instructions to reflect the change.

	* hfs.h:
	Added missing structure comments.

	* bdelete.c:
	Merge bdelete_brec() back into hfs_bdelete().
	Add missing function comments.


	* extent.c:
	Insignificant code change removing an unneeded indirection.

	* btree.c, hfs_btree.h, balloc.c, bnode.c:
	Add a 'sys_mdb' field to (struct hfs_btree).

	  Makefile:
	Move hfs_buffer_read() from hfs_sysdep.h to sysdep.c so it can use
	the symbol HFS_SECTOR_SIZE rather than the manifest constant 512.
	Have hfs_buffer_read() print an error message,
	and remove redundant errors from the callers.

	* hfs_sysdep.h, mdb.c, super.c, file.c, hfs.h, hfs_btree.h, catalog.c,
	  extent.c, btree.c, balloc.c, bfind.c, bnode.c:
	Get rid of the type hfs_device and the fields of that type,
	using the type hfs_sysmdb and the 'sys_mdb' field in its place.

	* Makefile:
	Fix definition of HDRS variable.

	* README.sgml, version.c:
	Bump version up to "pre-0.7-1".

	* Makefile:
	Separate sources and headers into three groups:
	B-tree code, HFS code and Linux code.

	* bitmap.c, bitops.c, hfs.h, hfs_sysdep.h, balloc.c:
	Implemented portable set of bit operations in hfs_sysdep.h

	* mdb.c, hfs_sysdep.h, hfs_btree.h, extent.c, btree.c, bitmap.c,
	  bnode.c, balloc.c:
	Implement a portable set of buffer operations in hfs_sysdep.h

	* TODO:
	Remove note about separating header files into two parts.

	* catalog.c:
	Remove call to hfs_mdb_dirty(), since the hfs_brec_relse() does it.

	* hfs.h, extent.c, file.c:
	Move hfs_getblk() from extent.c to file.c, since that is now the
	only file that actually uses it.

	* balloc.c:
	Replace use of hfs_getblk() in balloc.c with a local function
	(get_new_node()) that doesn't retry, since B-trees can't shrink.

	* hfs.h, hfs_btree.h, hfs_sysdep.h, mdb.c, extent.c:
	Make hfs_buffer a typedef.

	* inode.c, hfs.h, hfs_sysdep.h, dir.c:
	Change hfs_sysentry to a typedef.
	Rename 'sysentry' field of (struct hfs_cat_entry) to 'sys_entry'.

	* super.c, mdb.c, catalog.c:
	Rename hfs_cat_sync() to hfs_cat_commit() and call it
	from hfs_mdb_commit() rather than from hfs_write_super().

	* catalog.c, file.c:
	Minimize the calls to hfs_mdb_dirty().   Now called when:
	1) A buffer holding a volume bitmap block is dirtied.
	2) A dirty B-tree node is written back to the buffers.
	3) A dirty catalog entry is written back to the buffers.

	* hfs_sysdep.h, hfs.h:
	Make hfs_sysmdb a typedef.

Sun Aug 11 08:46:10 1996  Paul H. Hargrove  <[e-mail]>

	* hfs_sysdep.h, extent.c, hfs.h:
	Replace hfs_mdb_{lock,unlock} with more portable
	scheme using a wait queue in the MDB.

	* hfs.h, hfs_btree.h, hfs_sysdep.h, bnode.c, catalog.c, binsert.c:
	Make hfs_wait_queue a typedef'd pointer to a (struct wait_queue).
	Rename hfs_wait_on() to hfs_sleep_on().

	* catalog.c, hfs_sysdep.h, super.c, bfind.c, bnode.c, balloc.c:
	Implemented hfs_dev_name() in hfs_sysdep.h
	as a portable call to produce a device name.

	* super.c, hfs.h, mdb.c:
	Rename hfs_mdb_read() to hfs_mdb_get(), and don't take a
	'sys_mdb' argument.  That's the callers responsibility.

	* sysdep.c, Makefile:
	Remove the pointless file sysdep.c

	* README.sgml:
	Clean up the "System Requirements" section.

Sat Aug 10 22:41:24 1996  Paul H. Hargrove  <[e-mail]>

	* sysdep.h, sysdep.c, super.c, hfs_sysdep.h, mdb.c, string.c,
	  hfs_fs.h, hfs_fs_i.h, hfs_fs_sb.h, hfs_btree_private.h, hfs_btree.h,
	  file_cap.c, file_dbl.c, file_nat.c, hfs.h, file.c, dir_nat.c,
	  extent.c, dir.c, dir_cap.c, dir_dbl.c, catalog.c, bnode.c, brec.c,
	  btree.c, binsert.c, bitmap.c, bitops.c, bfind.c, bins_del.c,
	  Makefile, balloc.c, bdelete.c:
	Includes the hfs.h that was missing from the previous check in.
	MAJOR include-file cleanup:
		hfs_btree.h merged into hfs.h
		hfs_btree_private.h renamed hfs_btree.h
		sysdep.h renamed hfs_sysdep.h
	Fixed some minor portability fixes shown up by the header split.

	  bitops.c, bnode.c, brec.c, bins_del.c, binsert.c, bdelete.c, bfind.c,
	  balloc.c:
	Major split of hfs_fs.h into Linux-specific

	Move hfs_getblk() from file.c to extent.c

	* sysdep.h, super.c, mdb.c, hfs_fs_sb.h, hfs_fs.h, file.c, extent.c,
	  catalog.c, bnode.c, bitmap.c:
	Make the field 's_mdb' in (struct hfs_sb_info) a pointer to
	the MDB, rather than the actual MDB.  This allowed the definition
	of (struct hfs_mdb) to be moved from hfs_fs_sb.h to hfs_fs.h.

	* ccache.c, hfs_fs.h, Makefile, catalog.c:
	Merged ccache.c and catalog.c into the latter.
