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: RAW driver (CONFIG_RAW_DRIVER) |
10 | When: December 2005 | |
11 | Why: declared obsolete since kernel 2.6.3 | |
12 | O_DIRECT can be used instead | |
13 | Who: Adrian Bunk <bunk@stusta.de> | |

17 | What: drivers that were depending on OBSOLETE_OSS_DRIVER |
18 | (config options already removed) | |
19 | When: before 2.6.19 | |

20 | Why: OSS drivers with ALSA replacements |

a1446c7f | 25 | What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN |
d0aef39f | 26 | When: November 2006 |
a1446c7f JM |
27 | Why: Deprecated in favour of the new ioctl-based rawiso interface, which is |
28 | more efficient. You should really be using libraw1394 for raw1394 | |
29 | access anyway. | |

34 | What: sbp2: module parameter "force_inquiry_hack" |
35 | When: July 2006 | |
36 | Why: Superceded by parameter "workarounds". Both parameters are meant to be | |
37 | used ad-hoc and for single devices only, i.e. not in modprobe.conf, | |
38 | therefore the impact of this feature replacement should be low. | |

43 | What: Video4Linux API 1 ioctls and video_decoder.h from Video devices. |
44 | When: July 2006 | |
45 | Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6 | |
46 | series. The old API have lots of drawbacks and don't provide enough | |
47 | means to work with all video and audio standards. The newer API is | |
48 | already available on the main drivers and should be used instead. | |
49 | Newer drivers should use v4l_compat_translate_ioctl function to handle | |
50 | old calls, replacing to newer ones. | |
51 | Decoder iocts are using internally to allow video drivers to | |
52 | communicate with video decoders. This should also be improved to allow | |
53 | V4L2 calls being translated into compatible internal ioctls. | |

58 | What: remove EXPORT_SYMBOL(insert_resource) |
59 | When: April 2006 | |
60 | Files: kernel/resource.c | |
61 | Why: No modular usage in the kernel. | |

66 | What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl]) |
67 | When: November 2005 | |
68 | Files: drivers/pcmcia/: pcmcia_ioctl.c | |
69 | Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a | |
70 | normal hotpluggable bus, and with it using the default kernel | |
71 | infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA | |
72 | control ioctl needed by cardmgr and cardctl from pcmcia-cs is | |
73 | unnecessary, and makes further cleanups and integration of the | |
74 | PCMCIA subsystem into the Linux kernel device driver model more | |
75 | difficult. The features provided by cardmgr and cardctl are either | |
76 | handled by the kernel itself now or are available in the new | |
77 | pcmciautils package available at | |
78 | http://kernel.org/pub/linux/utils/kernel/pcmcia/ | |

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

95 | What: remove EXPORT_SYMBOL(kernel_thread) |
96 | When: August 2006 | |
97 | Files: arch/*/kernel/*_ksyms.c | |
98 | Why: kernel_thread is a low-level implementation detail. Drivers should | |
99 | use the <linux/kthread.h> API instead which shields them from | |
100 | implementation details and provides a higherlevel interface that | |
101 | prevents bugs and code duplication | |

106 | What: CONFIG_FORCED_INLINING |
107 | When: June 2006 | |
108 | Why: Config option is there to see if gcc is good enough. (in january | |
109 | 2006). If it is, the behavior should just be the default. If it's not, | |
110 | the option should just go away entirely. | |

115 | What: START_ARRAY ioctl for md |
116 | When: July 2006 | |
117 | Files: drivers/md/md.c | |
118 | Why: Not reliable by design - can fail when most needed. | |
119 | Alternatives exist | |

138 | What: Usage of invalid timevals in setitimer |
139 | When: March 2007 | |
140 | Why: POSIX requires to validate timevals in the setitimer call. This | |
141 | was never done by Linux. The invalid (e.g. negative timevals) were | |
142 | silently converted to more or less random timeouts and intervals. | |
143 | Until the removal a per boot limited number of warnings is printed | |
144 | and the timevals are sanitized. | |

150 | What: I2C interface of the it87 driver |
151 | When: January 2007 | |
152 | Why: The ISA interface is faster and should be always available. The I2C | |
153 | probing is also known to cause trouble in at least one case (see | |
154 | bug #5889.) | |

159 | What: Unused EXPORT_SYMBOL/EXPORT_SYMBOL_GPL exports |
160 | (temporary transition config option provided until then) | |
161 | The transition config option will also be removed at the same time. | |
162 | When: before 2.6.19 | |
163 | Why: Unused symbols are both increasing the size of the kernel binary | |
164 | and are often a sign of "wrong API" | |

169 | What: remove EXPORT_SYMBOL(tasklist_lock) |
170 | When: August 2006 | |
171 | Files: kernel/fork.c | |
172 | Why: tasklist_lock protects the kernel internal task list. Modules have | |
173 | no business looking at it, and all instances in drivers have been due | |
174 | to use of too-lowlevel APIs. Having this symbol exported prevents | |
175 | moving to more scalable locking schemes for the task list. | |

180 | What: mount/umount uevents |
181 | When: February 2007 | |
182 | Why: These events are not correct, and do not properly let userspace know | |
183 | when a file system has been mounted or unmounted. Userspace should | |
184 | poll the /proc/mounts file instead to detect this properly. | |

189 | What: USB driver API moves to EXPORT_SYMBOL_GPL |
190 | When: Febuary 2008 | |
191 | Files: include/linux/usb.h, drivers/usb/core/driver.c | |
192 | Why: The USB subsystem has changed a lot over time, and it has been | |
193 | possible to create userspace USB drivers using usbfs/libusb/gadgetfs | |
194 | that operate as fast as the USB bus allows. Because of this, the USB | |
195 | subsystem will not be allowing closed source kernel drivers to | |
196 | register with it, after this grace period is over. If anyone needs | |
197 | any help in converting their closed source drivers over to use the | |
198 | userspace filesystems, please contact the | |
199 | linux-usb-devel@lists.sourceforge.net mailing list, and the developers | |
200 | there will be glad to help you out. | |

205 | What: find_trylock_page | |
206 | When: January 2007 | |
207 | Why: The interface no longer has any callers left in the kernel. It | |
208 | is an odd interface (compared with other find_*_page functions), in | |
209 | that it does not take a refcount to the page, only the page lock. | |
210 | It should be replaced with find_get_page or find_lock_page if possible. | |
211 | This feature removal can be reevaluated if users of the interface | |
212 | cannot cleanly use something else. | |

225 | What: Support for the Momentum / PMC-Sierra Jaguar ATX evaluation board | |
226 | When: September 2006 | |
227 | Why: Does no longer build since quite some time, and was never popular, | |
228 | due to the platform being replaced by successor models. Apparently | |
229 | no user base left. It also is one of the last users of | |
230 | WANT_PAGE_VIRTUAL. | |

254 | no user base left for these platforms. Hardware out of production | |
255 | since several years and hardly a trace of the manufacturer left on | |
256 | the net. | |
