Follow-ups

--- Michael Hennerich 2010-06-15 08:39:54

This bug is caused due to the fact that CONFIG_PCMCIA_IOCTL (obsolete) is not

selected.

Read below:

config PCMCIA_IOCTL

bool "PCMCIA control ioctl (obsolete)"

depends on PCMCIA && ARM && !SMP && !PREEMPT

default y

help

If you say Y here, the deprecated ioctl interface to the PCMCIA

subsystem will be built. It is needed by the deprecated pcmcia-cs

tools (cardmgr, cardctl) to function properly.

You should use the new pcmciautils package instead (see

<file:Documentation/Changes> for location and details).

This config option will most likely be removed from kernel 2.6.35,

the associated code from kernel 2.6.36.

As the PCMCIA ioctl is not locking safe, it depends on !SMP and

!PREEMPT.

If unsure, say N.

Since this will be removed anyways - I see no point supporting it any further.

Please remove the failing test cases!

These tools are not really needed!

I tested that hot plugging PCMCIA cards still works...

Michael,

The old document based on pcmcia-cs cardctl is also out of date. Could you

please update the document with new pcmica_socket tools?
