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. | |

| 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> | |

| 26 | --------------------------- | |
| 27 | ||
| 28 | What: PCI Name Database (CONFIG_PCI_NAMES) | |
| 29 | When: July 2005 | |
| 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. | |

| 36 | ||
| 37 | What: io_remap_page_range() (macro or function) | |
| 38 | When: September 2005 | |
| 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. | |

46 | What: RAW driver (CONFIG_RAW_DRIVER) |
| 47 | When: December 2005 | |
| 48 | Why: declared obsolete since kernel 2.6.3 | |
| 49 | O_DIRECT can be used instead | |

54 | What: register_ioctl32_conversion() / unregister_ioctl32_conversion() |
| 55 | When: April 2005 | |
| 56 | Why: Replaced by ->compat_ioctl in file_operations and other method | |
| 57 | vecors. | |

| 62 | What: RCU API moves to EXPORT_SYMBOL_GPL | |
| 63 | When: April 2006 | |
| 64 | Files: include/linux/rcupdate.h, kernel/rcupdate.c | |
| 65 | Why: 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. | |

77 | What: remove verify_area() |
| 78 | When: July 2006 | |
| 79 | Files: Various uaccess.h headers. | |
| 80 | Why: Deprecated and redundant. access_ok() should be used instead. | |
| 81 | Who: Jesper Juhl <juhl-lkml@dif.dk> | |

85 | What: IEEE1394 Audio and Music Data Transmission Protocol driver, |
| 86 | Connection Management Procedures driver | |
| 87 | When: November 2005 | |
| 88 | Files: drivers/ieee1394/{amdtp,cmp}* | |
| 89 | Why: These are incomplete, have never worked, and are better implemented | |
| 90 | in userland via raw1394 (see http://freebob.sourceforge.net/ for | |
| 91 | example.) | |
| 92 | Who: Jody McIntyre <scjody@steamballoon.com> | |
| 93 | ||
| 94 | --------------------------- | |
| 95 | ||
| 96 | What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN | |
| 97 | When: November 2005 | |
| 98 | Why: 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. | |

105 | What: register_serial/unregister_serial |
| 106 | When: December 2005 | |
| 107 | Why: 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. | |

115 | What: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid |
| 116 | When: November 2005 | |
| 117 | Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c | |
| 118 | Why: Match the other drivers' name for the same function, duplicate names | |
| 119 | will be available until removal of old names. | |
