[2.6 patch] the long overdue pcmcia_ioctl.c removal
From: Adrian Bunk
Date: Wed Feb 13 2008 - 16:51:52 EST
pcmcia_ioctl.c was scheduled for removal in 2005, and it has a
deprecation printk() since 2005 (sic).
This patch contains the long overdue removal and the cleanups that are
now possible.

-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@xxxxxxxx>
-
----------------------------

What: sys_sysctl
When: September 2010
Option: CONFIG_SYSCTL_SYSCALL

- 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

-
- Bind_device() associates a device driver with a particular socket.

- 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

- allocates the client structure that will be used.
