Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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. |

| 9 | What: devfs |
| 10 | When: July 2005 |
| 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> |
| 17 | |
| 18 | --------------------------- |
| 19 | |
| 20 | What: ACPI S4bios support |
| 21 | When: May 2005 |
| 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> |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 28 | What: io_remap_page_range() (macro or function) |
| 29 | When: September 2005 |
| 30 | Why: Replaced by io_remap_pfn_range() which allows more memory space |
| 31 | addressabilty (by using a pfn) and supports sparc & sparc64 |
| 32 | iospace as part of the pfn. |

Adrian Bunk | 98e7f29 | 2005-06-25 14:59:37 -0700 | [diff] [blame] | 37 | What: RAW driver (CONFIG_RAW_DRIVER) |
| 38 | When: December 2005 |
| 39 | Why: declared obsolete since kernel 2.6.3 |
| 40 | O_DIRECT can be used instead |
| 41 | Who: Adrian Bunk <bunk@stusta.de> |

Paul E. McKenney | 66cf8f1 | 2005-05-01 08:59:03 -0700 | [diff] [blame] | 45 | What: RCU API moves to EXPORT_SYMBOL_GPL |
| 46 | When: April 2006 |
| 47 | Files: include/linux/rcupdate.h, kernel/rcupdate.c |
| 48 | Why: Outside of Linux, the only implementations of anything even |
| 49 | vaguely resembling RCU that I am aware of are in DYNIX/ptx, |
| 50 | VM/XA, Tornado, and K42. I do not expect anyone to port binary |
| 51 | drivers or kernel modules from any of these, since the first two |
| 52 | are owned by IBM and the last two are open-source research OSes. |
| 53 | So these will move to GPL after a grace period to allow |
| 54 | people, who might be using implementations that I am not aware |
| 55 | of, to adjust to this upcoming change. |

| 58 | --------------------------- |
| 59 | |
| 60 | What: IEEE1394 Audio and Music Data Transmission Protocol driver, |
| 61 | Connection Management Procedures driver |
| 62 | When: November 2005 |
| 63 | Files: drivers/ieee1394/{amdtp,cmp}* |
| 64 | Why: These are incomplete, have never worked, and are better implemented |
| 65 | in userland via raw1394 (see http://freebob.sourceforge.net/ for |
| 66 | example.) |
| 67 | Who: Jody McIntyre <scjody@steamballoon.com> |
| 68 | |
| 69 | --------------------------- |
| 70 | |
| 71 | What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN |
| 72 | When: November 2005 |
| 73 | Why: Deprecated in favour of the new ioctl-based rawiso interface, which is |
| 74 | more efficient. You should really be using libraw1394 for raw1394 |
| 75 | access anyway. |

| 78 | --------------------------- |
| 79 | |
| 80 | What: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid |
| 81 | When: November 2005 |
| 82 | Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c |
| 83 | Why: Match the other drivers' name for the same function, duplicate names |
| 84 | will be available until removal of old names. |

Dominik Brodowski | bf45d9b0 | 2005-07-07 17:58:58 -0700 | [diff] [blame] | 87 | --------------------------- |
| 88 | |
| 89 | What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl]) |
| 90 | When: November 2005 |
| 91 | Files: drivers/pcmcia/: pcmcia_ioctl.c |
| 92 | Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a |
| 93 | normal hotpluggable bus, and with it using the default kernel |
| 94 | infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA |
| 95 | control ioctl needed by cardmgr and cardctl from pcmcia-cs is |
| 96 | unnecessary, and makes further cleanups and integration of the |
| 97 | PCMCIA subsystem into the Linux kernel device driver model more |
| 98 | difficult. The features provided by cardmgr and cardctl are either |
| 99 | handled by the kernel itself now or are available in the new |
| 100 | pcmciautils package available at |
| 101 | http://kernel.org/pub/linux/utils/kernel/pcmcia/ |

| 104 | --------------------------- |
| 105 | |
| 106 | What: ip_queue and ip6_queue (old ipv4-only and ipv6-only netfilter queue) |
| 107 | When: December 2005 |
| 108 | Why: This interface has been obsoleted by the new layer3-independent |
| 109 | "nfnetlink_queue". The Kernel interface is compatible, so the old |
| 110 | ip[6]tables "QUEUE" targets still work and will transparently handle |
| 111 | all packets into nfnetlink queue number 0. Userspace users will have |
| 112 | to link against API-compatible library on top of libnfnetlink_queue |
| 113 | instead of the current 'libipq'. |
