| The following is a list of files and features that are going to be |
| removed in the kernel source tree. Every entry should contain what |
| exactly is going away, why it is happening, and who is going to be doing |
| the work. When the feature is removed from the kernel, it should also |
| be removed from this file. |
| |
| --------------------------- |
| |
| What: devfs |
| When: July 2005 |
| Files: fs/devfs/*, include/linux/devfs_fs*.h and assorted devfs |
| function calls throughout the kernel tree |
| Why: It has been unmaintained for a number of years, has unfixable |
| races, contains a naming policy within the kernel that is |
| against the LSB, and can be replaced by using udev. |
| Who: Greg Kroah-Hartman <greg@kroah.com> |
| |
| --------------------------- |
| |
| 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: drivers depending on OBSOLETE_OSS_DRIVER |
| When: January 2006 |
| Why: OSS drivers with ALSA replacements |
| Who: Adrian Bunk <bunk@stusta.de> |
| |
| --------------------------- |
| |
| What: RCU API moves to EXPORT_SYMBOL_GPL |
| When: April 2006 |
| Files: include/linux/rcupdate.h, kernel/rcupdate.c |
| Why: Outside of Linux, the only implementations of anything even |
| vaguely resembling RCU that I am aware of are in DYNIX/ptx, |
| VM/XA, Tornado, and K42. I do not expect anyone to port binary |
| drivers or kernel modules from any of these, since the first two |
| are owned by IBM and the last two are open-source research OSes. |
| So these will move to GPL after a grace period to allow |
| people, who might be using implementations that I am not aware |
| of, to adjust to this upcoming change. |
| Who: Paul E. McKenney <paulmck@us.ibm.com> |
| |
| --------------------------- |
| |
| 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: i2c sysfs name change: in1_ref, vid deprecated in favour of cpu0_vid |
| When: November 2005 |
| Files: drivers/i2c/chips/adm1025.c, drivers/i2c/chips/adm1026.c |
| Why: Match the other drivers' name for the same function, duplicate names |
| will be available until removal of old names. |
| Who: Grant Coady <gcoady@gmail.com> |
| |
| --------------------------- |
| |
| What: remove EXPORT_SYMBOL(panic_timeout) |
| When: April 2006 |
| Files: kernel/panic.c |
| Why: No modular usage in the kernel. |
| Who: Adrian Bunk <bunk@stusta.de> |
| |
| --------------------------- |
| |
| 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> |
