1 The following is a list of files and features that are going to be
2 removed in the kernel source tree. Every entry should contain what
3 exactly is going away, why it is happening, and who is going to be doing
4 the work. When the feature is removed from the kernel, it should also
5 be removed from this file.
7 ---------------------------
11 Files: fs/devfs/*, include/linux/devfs_fs*.h and assorted devfs
12 function calls throughout the kernel tree
13 Why: 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.
16 Who: Greg Kroah-Hartman <greg@kroah.com>
18 ---------------------------
20 What: ACPI S4bios support
22 Why: Noone uses it, and it probably does not work, anyway. swsusp is
23 faster, more reliable, and people are actually using it.
24 Who: Pavel Machek <pavel@suse.cz>
26 ---------------------------
28 What: PCI Name Database (CONFIG_PCI_NAMES)
30 Why: 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.
33 Who: Greg Kroah-Hartman <gregkh@suse.de>
35 ---------------------------
37 What: io_remap_page_range() (macro or function)
39 Why: 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.
42 Who: Randy Dunlap <rddunlap@osdl.org>
44 ---------------------------
46 What: register_ioctl32_conversion() / unregister_ioctl32_conversion()
48 Why: Replaced by ->compat_ioctl in file_operations and other method
50 Who: Andi Kleen <ak@muc.de>, Christoph Hellwig <hch@lst.de>
52 ---------------------------
54 What: RCU API moves to EXPORT_SYMBOL_GPL
56 Files: include/linux/rcupdate.h, kernel/rcupdate.c
57 Why: 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.
65 Who: Paul E. McKenney <paulmck@us.ibm.com>
67 ---------------------------
69 What: IEEE1394 Audio and Music Data Transmission Protocol driver,
70 Connection Management Procedures driver
72 Files: drivers/ieee1394/{amdtp,cmp}*
73 Why: These are incomplete, have never worked, and are better implemented
74 in userland via raw1394 (see http://freebob.sourceforge.net/ for
76 Who: Jody McIntyre <scjody@steamballoon.com>
78 ---------------------------
80 What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
82 Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
83 more efficient. You should really be using libraw1394 for raw1394
