Linus Torvalds1da177e2005-04-16 15:20:36 -07001The following is a list of files and features that are going to be
2removed in the kernel source tree. Every entry should contain what
3exactly is going away, why it is happening, and who is going to be doing
4the work. When the feature is removed from the kernel, it should also
5be removed from this file.

7---------------------------
8
9What: devfs
10When: July 2005
11Files: fs/devfs/*, include/linux/devfs_fs*.h and assorted devfs
12 function calls throughout the kernel tree
13Why: It has been unmaintained for a number of years, has unfixable
14 races, contains a naming policy within the kernel that is
15 against the LSB, and can be replaced by using udev.
16Who: Greg Kroah-Hartman <greg@kroah.com>
17
18---------------------------
19
20What: ACPI S4bios support
21When: May 2005
22Why: Noone uses it, and it probably does not work, anyway. swsusp is
23 faster, more reliable, and people are actually using it.
24Who: Pavel Machek <pavel@suse.cz>
25
26---------------------------
27
28What: PCI Name Database (CONFIG_PCI_NAMES)
29When: July 2005
30Why: It bloats the kernel unnecessarily, and is handled by userspace better
31 (pciutils supports it.) Will eliminate the need to try to keep the
32 pci.ids file in sync with the sf.net database all of the time.
33Who: Greg Kroah-Hartman <gregkh@suse.de>
34
35---------------------------
36
37What: io_remap_page_range() (macro or function)
38When: September 2005
39Why: Replaced by io_remap_pfn_range() which allows more memory space
40 addressabilty (by using a pfn) and supports sparc & sparc64
41 iospace as part of the pfn.
42Who: Randy Dunlap <rddunlap@osdl.org>
Christoph Hellwig22a685d2005-04-16 15:25:48 -070043
44---------------------------
45
46What: register_ioctl32_conversion() / unregister_ioctl32_conversion()
47When: April 2005
48Why: Replaced by ->compat_ioctl in file_operations and other method
49 vecors.
50Who: Andi Kleen <ak@muc.de>, Christoph Hellwig <hch@lst.de>
Paul E. McKenney66cf8f12005-05-01 08:59:03 -070051
52---------------------------
53
54What: RCU API moves to EXPORT_SYMBOL_GPL
55When: April 2006
56Files: include/linux/rcupdate.h, kernel/rcupdate.c
57Why: Outside of Linux, the only implementations of anything even
58 vaguely resembling RCU that I am aware of are in DYNIX/ptx,
59 VM/XA, Tornado, and K42. I do not expect anyone to port binary
60 drivers or kernel modules from any of these, since the first two
61 are owned by IBM and the last two are open-source research OSes.
62 So these will move to GPL after a grace period to allow
63 people, who might be using implementations that I am not aware
64 of, to adjust to this upcoming change.

67---------------------------
68
Jesper Juhl451512f2005-06-23 00:10:28 -070069What: remove verify_area()
70When: July 2006
71Files: Various uaccess.h headers.
72Why: Deprecated and redundant. access_ok() should be used instead.
73Who: Jesper Juhl <juhl-lkml@dif.dk>
74
75---------------------------
76
Jody McIntyrea1446c72005-05-16 21:53:59 -070077What: IEEE1394 Audio and Music Data Transmission Protocol driver,
78 Connection Management Procedures driver
79When: November 2005
80Files: drivers/ieee1394/{amdtp,cmp}*
81Why: These are incomplete, have never worked, and are better implemented
82 in userland via raw1394 (see http://freebob.sourceforge.net/ for
83 example.)
84Who: Jody McIntyre <scjody@steamballoon.com>
85
86---------------------------
87
88What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
89When: November 2005
90Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
91 more efficient. You should really be using libraw1394 for raw1394
92 access anyway.
93Who: Jody McIntyre <scjody@steamballoon.com>

Russell Kinga8ad86f2005-06-23 14:23:35 +010097What: register_serial/unregister_serial
98When: December 2005
99Why: This interface does not allow serial ports to be registered against
100 a struct device, and as such does not allow correct power management
101 of such ports. 8250-based ports should use serial8250_register_port
102 and serial8250_unregister_port instead.

Grant Coady937df8d2005-05-12 11:59:29 +1000107What: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid
108When: November 2005
109Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c
110Why: Match the other drivers' name for the same function, duplicate names
111 will be available until removal of old names.
