---------------------------
-What: ACPI S4bios support
-When: May 2005
-Why: Noone uses it, and it probably does not work, anyway. swsusp is
- faster, more reliable, and people are actually using it.
-Who: Pavel Machek <pavel@suse.cz>
+What: RAW driver (CONFIG_RAW_DRIVER)
+When: December 2005
+Why: declared obsolete since kernel 2.6.3
+ O_DIRECT can be used instead
+Who: Adrian Bunk <bunk@stusta.de>
---------------------------
-What: PCI Name Database (CONFIG_PCI_NAMES)
-When: July 2005
-Why: It bloats the kernel unnecessarily, and is handled by userspace better
- (pciutils supports it.) Will eliminate the need to try to keep the
- pci.ids file in sync with the sf.net database all of the time.
-Who: Greg Kroah-Hartman <gregkh@suse.de>
-
----------------------------
-
-What: io_remap_page_range() (macro or function)
-When: September 2005
-Why: Replaced by io_remap_pfn_range() which allows more memory space
- addressabilty (by using a pfn) and supports sparc & sparc64
- iospace as part of the pfn.
-Who: Randy Dunlap <rddunlap@osdl.org>
-
----------------------------
-
-What: register_ioctl32_conversion() / unregister_ioctl32_conversion()
-When: April 2005
-Why: Replaced by ->compat_ioctl in file_operations and other method
- vecors.
-Who: Andi Kleen <ak@muc.de>, Christoph Hellwig <hch@lst.de>
+What: drivers that were depending on OBSOLETE_OSS_DRIVER
+ (config options already removed)
+When: before 2.6.19
+Why: OSS drivers with ALSA replacements
+Who: Adrian Bunk <bunk@stusta.de>
---------------------------
---------------------------
-What: IEEE1394 Audio and Music Data Transmission Protocol driver,
- Connection Management Procedures driver
-When: November 2005
-Files: drivers/ieee1394/{amdtp,cmp}*
-Why: These are incomplete, have never worked, and are better implemented
- in userland via raw1394 (see http://freebob.sourceforge.net/ for
- example.)
-Who: Jody McIntyre <scjody@steamballoon.com>
-
----------------------------
-
What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
When: November 2005
Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
more efficient. You should really be using libraw1394 for raw1394
access anyway.
Who: Jody McIntyre <scjody@steamballoon.com>
+
+---------------------------
+
+What: sbp2: module parameter "force_inquiry_hack"
+When: July 2006
+Why: Superceded by parameter "workarounds". Both parameters are meant to be
+ used ad-hoc and for single devices only, i.e. not in modprobe.conf,
+ therefore the impact of this feature replacement should be low.
+Who: Stefan Richter <stefanr@s5r6.in-berlin.de>
+
+---------------------------
+
+What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
+When: July 2006
+Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6
+ series. The old API have lots of drawbacks and don't provide enough
+ means to work with all video and audio standards. The newer API is
+ already available on the main drivers and should be used instead.
+ Newer drivers should use v4l_compat_translate_ioctl function to handle
+ old calls, replacing to newer ones.
+ Decoder iocts are using internally to allow video drivers to
+ communicate with video decoders. This should also be improved to allow
+ V4L2 calls being translated into compatible internal ioctls.
+Who: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
+
+---------------------------
+
+What: remove EXPORT_SYMBOL(insert_resource)
+When: April 2006
+Files: kernel/resource.c
+Why: No modular usage in the kernel.
+Who: Adrian Bunk <bunk@stusta.de>
+
+---------------------------
+
+What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
+When: November 2005
+Files: drivers/pcmcia/: pcmcia_ioctl.c
+Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a
+ normal hotpluggable bus, and with it using the default kernel
+ infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA
+ control ioctl needed by cardmgr and cardctl from pcmcia-cs is
+ unnecessary, and makes further cleanups and integration of the
+ PCMCIA subsystem into the Linux kernel device driver model more
+ difficult. The features provided by cardmgr and cardctl are either
+ handled by the kernel itself now or are available in the new
+ pcmciautils package available at
+ http://kernel.org/pub/linux/utils/kernel/pcmcia/
+Who: Dominik Brodowski <linux@brodo.de>
+
+---------------------------
+
+What: ip_queue and ip6_queue (old ipv4-only and ipv6-only netfilter queue)
+When: December 2005
+Why: This interface has been obsoleted by the new layer3-independent
+ "nfnetlink_queue". The Kernel interface is compatible, so the old
+ ip[6]tables "QUEUE" targets still work and will transparently handle
+ all packets into nfnetlink queue number 0. Userspace users will have
+ to link against API-compatible library on top of libnfnetlink_queue
+ instead of the current 'libipq'.
+Who: Harald Welte <laforge@netfilter.org>
+
+---------------------------
+
+What: remove EXPORT_SYMBOL(kernel_thread)
+When: August 2006
+Files: arch/*/kernel/*_ksyms.c
+Why: kernel_thread is a low-level implementation detail. Drivers should
+ use the <linux/kthread.h> API instead which shields them from
+ implementation details and provides a higherlevel interface that
+ prevents bugs and code duplication
+Who: Christoph Hellwig <hch@lst.de>
+
+---------------------------
+
+What: CONFIG_FORCED_INLINING
+When: June 2006
+Why: Config option is there to see if gcc is good enough. (in january
+ 2006). If it is, the behavior should just be the default. If it's not,
+ the option should just go away entirely.
+Who: Arjan van de Ven
+
+---------------------------
+
+What: START_ARRAY ioctl for md
+When: July 2006
+Files: drivers/md/md.c
+Why: Not reliable by design - can fail when most needed.
+ Alternatives exist
+Who: NeilBrown <neilb@suse.de>
+
+---------------------------
+
+What: au1x00_uart driver
+When: January 2006
+Why: The 8250 serial driver now has the ability to deal with the differences
+ between the standard 8250 family of UARTs and their slightly strange
+ brother on Alchemy SOCs. The loss of features is not considered an
+ issue.
+Who: Ralf Baechle <ralf@linux-mips.org>
+
+---------------------------
+
+What: eepro100 network driver
+When: January 2007
+Why: replaced by the e100 driver
+Who: Adrian Bunk <bunk@stusta.de>
+
+---------------------------
+
+What: pci_module_init(driver)
+When: January 2007
+Why: Is replaced by pci_register_driver(pci_driver).
+Who: Richard Knutsson <ricknu-0@student.ltu.se> and Greg Kroah-Hartman <gregkh@suse.de>
+
+---------------------------
+
+What: Usage of invalid timevals in setitimer
+When: March 2007
+Why: POSIX requires to validate timevals in the setitimer call. This
+ was never done by Linux. The invalid (e.g. negative timevals) were
+ silently converted to more or less random timeouts and intervals.
+ Until the removal a per boot limited number of warnings is printed
+ and the timevals are sanitized.
+
+Who: Thomas Gleixner <tglx@linutronix.de>
+
+---------------------------
+
+What: I2C interface of the it87 driver
+When: January 2007
+Why: The ISA interface is faster and should be always available. The I2C
+ probing is also known to cause trouble in at least one case (see
+ bug #5889.)
+Who: Jean Delvare <khali@linux-fr.org>
+
+---------------------------
+
+What: remove EXPORT_SYMBOL(tasklist_lock)
+When: August 2006
+Files: kernel/fork.c
+Why: tasklist_lock protects the kernel internal task list. Modules have
+ no business looking at it, and all instances in drivers have been due
+ to use of too-lowlevel APIs. Having this symbol exported prevents
+ moving to more scalable locking schemes for the task list.
+Who: Christoph Hellwig <hch@lst.de>
+
+---------------------------
+
+What: mount/umount uevents
+When: February 2007
+Why: These events are not correct, and do not properly let userspace know
+ when a file system has been mounted or unmounted. Userspace should
+ poll the /proc/mounts file instead to detect this properly.
+Who: Greg Kroah-Hartman <gregkh@suse.de>
+
+---------------------------
+
+What: Support for NEC DDB5074 and DDB5476 evaluation boards.
+When: June 2006
+Why: Board specific code doesn't build anymore since ~2.6.0 and no
+ users have complained indicating there is no more need for these
+ boards. This should really be considered a last call.
+Who: Ralf Baechle <ralf@linux-mips.org>
+
+---------------------------
+
+What: USB driver API moves to EXPORT_SYMBOL_GPL
+When: Febuary 2008
+Files: include/linux/usb.h, drivers/usb/core/driver.c
+Why: The USB subsystem has changed a lot over time, and it has been
+ possible to create userspace USB drivers using usbfs/libusb/gadgetfs
+ that operate as fast as the USB bus allows. Because of this, the USB
+ subsystem will not be allowing closed source kernel drivers to
+ register with it, after this grace period is over. If anyone needs
+ any help in converting their closed source drivers over to use the
+ userspace filesystems, please contact the
+ linux-usb-devel@lists.sourceforge.net mailing list, and the developers
+ there will be glad to help you out.
+Who: Greg Kroah-Hartman <gregkh@suse.de>
+
+---------------------------
+
+What: find_trylock_page
+When: January 2007
+Why: The interface no longer has any callers left in the kernel. It
+ is an odd interface (compared with other find_*_page functions), in
+ that it does not take a refcount to the page, only the page lock.
+ It should be replaced with find_get_page or find_lock_page if possible.
+ This feature removal can be reevaluated if users of the interface
+ cannot cleanly use something else.
