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: 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: 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: 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: 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: 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: remove verify_area()
|
|
When: July 2006
|
|
Files: Various uaccess.h headers.
|
|
Why: Deprecated and redundant. access_ok() should be used instead.
|
|
Who: Jesper Juhl <juhl-lkml@dif.dk>
|
|
|
|
---------------------------
|
|
|
|
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: register_serial/unregister_serial
|
|
When: September 2005
|
|
Why: This interface does not allow serial ports to be registered against
|
|
a struct device, and as such does not allow correct power management
|
|
of such ports. 8250-based ports should use serial8250_register_port
|
|
and serial8250_unregister_port, or platform devices instead.
|
|
Who: Russell King <rmk@arm.linux.org.uk>
|
|
|
|
---------------------------
|
|
|
|
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: 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/
|
