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>

44---------------------------
45
Adrian Bunk98e7f292005-06-25 14:59:37 -070046What: RAW driver (CONFIG_RAW_DRIVER)
47When: December 2005
48Why: declared obsolete since kernel 2.6.3
49 O_DIRECT can be used instead
50Who: Adrian Bunk <bunk@stusta.de>
51
52---------------------------
53
Christoph Hellwig22a685d2005-04-16 15:25:48 -070054What: register_ioctl32_conversion() / unregister_ioctl32_conversion()
55When: April 2005
56Why: Replaced by ->compat_ioctl in file_operations and other method
57 vecors.
58Who: Andi Kleen <ak@muc.de>, Christoph Hellwig <hch@lst.de>

62What: RCU API moves to EXPORT_SYMBOL_GPL
63When: April 2006
64Files: include/linux/rcupdate.h, kernel/rcupdate.c
65Why: Outside of Linux, the only implementations of anything even
66 vaguely resembling RCU that I am aware of are in DYNIX/ptx,
67 VM/XA, Tornado, and K42. I do not expect anyone to port binary
68 drivers or kernel modules from any of these, since the first two
69 are owned by IBM and the last two are open-source research OSes.
70 So these will move to GPL after a grace period to allow
71 people, who might be using implementations that I am not aware
72 of, to adjust to this upcoming change.

Jesper Juhl451512f2005-06-23 00:10:28 -070077What: remove verify_area()
78When: July 2006
79Files: Various uaccess.h headers.
80Why: Deprecated and redundant. access_ok() should be used instead.
81Who: Jesper Juhl <juhl-lkml@dif.dk>
82
83---------------------------
84
Jody McIntyrea1446c72005-05-16 21:53:59 -070085What: IEEE1394 Audio and Music Data Transmission Protocol driver,
86 Connection Management Procedures driver
87When: November 2005
88Files: drivers/ieee1394/{amdtp,cmp}*
89Why: These are incomplete, have never worked, and are better implemented
90 in userland via raw1394 (see http://freebob.sourceforge.net/ for
91 example.)
92Who: Jody McIntyre <scjody@steamballoon.com>
93
94---------------------------
95
96What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
97When: November 2005
98Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
99 more efficient. You should really be using libraw1394 for raw1394
100 access anyway.

Russell Kinga8ad86f2005-06-23 14:23:35 +0100105What: register_serial/unregister_serial
106When: December 2005
107Why: This interface does not allow serial ports to be registered against
108 a struct device, and as such does not allow correct power management
109 of such ports. 8250-based ports should use serial8250_register_port
110 and serial8250_unregister_port instead.

Grant Coady937df8d2005-05-12 11:59:29 +1000115What: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid
116When: November 2005
117Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c
118Why: Match the other drivers' name for the same function, duplicate names
119 will be available until removal of old names.
