-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

-
- bind_request() connects a socket to a particular client driver.
- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance
- of the device. unbind_request() deletes a driver instance.
-
- Bind_device() associates a device driver with a particular socket.
- It is normally called by Driver Services after it has identified
- a newly inserted card. An instance of that driver will then be
- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the
- caller with a socket. The driver must have already been bound
- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.

How about moving the pcmcia ioctl entry from feature-removal-schedule.txt to a
new file (say...removed-features.txt) so that its easy to find a list of
removed features and why /when they were removed when upgrading the kernel?

Vetoed. I'll push the pcmcia_ioctl.c removal when the few remaining issues
with the new pcmciautils interface are solved.

-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

-
- bind_request() connects a socket to a particular client driver.
- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance
- of the device. unbind_request() deletes a driver instance.
-
- Bind_device() associates a device driver with a particular socket.
- It is normally called by Driver Services after it has identified
- a newly inserted card. An instance of that driver will then be
- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the
- caller with a socket. The driver must have already been bound
- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.

There are still systems around which (a) use cardmgr rather than the new
pcmcia utils, and (b) applications make direct ioctl calls to the kernel
PCMCIA layer external to the pcmcia-cs packages.
Like it or not, the PCMCIA ioctls are a well-established API.
