What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: December 2006
Files: include/linux/video_decoder.h
+Check: include/linux/video_decoder.h
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
What: remove EXPORT_SYMBOL(kernel_thread)
When: August 2006
Files: arch/*/kernel/*_ksyms.c
-Funcs: kernel_thread
+Check: kernel_thread
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
---------------------------
+What: vm_ops.nopage
+When: Soon, provided in-kernel callers have been converted
+Why: This interface is replaced by vm_ops.fault, but it has been around
+ forever, is used by a lot of drivers, and doesn't cost much to
+ maintain.

What: Interrupt only SA_* flags
When: September 2007
Why: The interrupt related SA_* flags are replaced by IRQF_* to move them
---------------------------
-What: i2c-isa
-When: December 2006
-Why: i2c-isa is a non-sense and doesn't fit in the device driver
- model. Drivers relying on it are better implemented as platform
- drivers.

What: i2c_adapter.list
When: July 2007
Why: Superfluous, this list duplicates the one maintained by the driver
---------------------------
-What: /sys/firmware/acpi/namespace
-When: 2.6.21
-Why: The ACPI namespace is effectively the symbol list for
- the BIOS. The device names are completely arbitrary
- and have no place being exposed to user-space.
-
- For those interested in the BIOS ACPI namespace,
- the BIOS can be extracted and disassembled with acpidump
- and iasl as documented in the pmtools package here:

What: ACPI procfs interface
-When: July 2007
-Why: After ACPI sysfs conversion, ACPI attributes will be duplicated
- in sysfs and the ACPI procfs interface should be removed.
+When: July 2008
+Why: ACPI sysfs conversion should be finished by January 2008.
+ ACPI procfs interface will be removed in July 2008 so that
+ there is enough time for the user space to catch up.

+What: /proc/acpi/event
+When: February 2008
+Why: /proc/acpi/event has been replaced by events via the input layer
+ and netlink since 2.6.23.

---------------------------
-What: read_dev_chars(), read_conf_data{,_lpm}() (s390 common I/O layer)
-When: December 2007
-Why: These functions are a leftover from 2.4 times. They have several
- problems:
- - Duplication of checks that are done in the device driver's
- interrupt handler
- - common I/O layer can't do device specific error recovery
- - device driver can't be notified for conditions happening during
- execution of the function
- Device drivers should issue the read device characteristics and read
- configuration data ccws and do the appropriate error handling
- themselves.

What: i2c-ixp2000, i2c-ixp4xx and scx200_i2c drivers
When: September 2007
Why: Obsolete. The new i2c-gpio driver replaces all hardware-specific
