MODULE_EXIT(9) Driver Basics MODULE_EXIT(9)NAME
module_exit - driver exit entry point
SYNOPSIS
module_exit(x);
ARGUMENTS
x
function to be run when driver is removed
DESCRIPTION
module_exit will wrap the driver clean-up code with cleanup_module when used with rmmod when the driver is a module. If the driver is
statically compiled into the kernel, module_exit has no effect. There can only be one per module.

STRUCT USB_DEVICE_DR(9) Host-Side Data Types and Macro STRUCT USB_DEVICE_DR(9)NAME
struct_usb_device_driver - identifies USB device driver to usbcore
SYNOPSIS
struct usb_device_driver {
const char * name;
int (* probe) (struct usb_device *udev);
void (* disconnect) (struct usb_device *udev);
int (* suspend) (struct usb_device *udev, pm_message_t message);
int (* resume) (struct usb_device *udev, pm_message_t message);
struct usbdrv_wrap drvwrap;
unsigned int supports_autosuspend:1;
};
MEMBERS
name
The driver name should be unique among USB drivers, and should normally be the same as the module name.
probe
Called to see if the driver is willing to manage a particular device. If it is, probe returns zero and uses dev_set_drvdata to
associate driver-specific data with the device. If unwilling to manage the device, return a negative errno value.
disconnect
Called when the device is no longer accessible, usually because it has been (or is being) disconnected or the driver's module is being
unloaded.
suspend
Called when the device is going to be suspended by the system.
resume
Called when the device is being resumed by the system.
drvwrap
Driver-model core structure wrapper.
supports_autosuspend
if set to 0, the USB core will not allow autosuspend for devices bound to this driver.
DESCRIPTION
USB drivers must provide all the fields listed above except drvwrap.

Hi There,
I want to make sure that kmem_cache_alloc is not called concurrently with kmem_cache_destroy on module exit and I want be able to use GFP_KERNEL for the kmem_cache_alloc calls.
Would a read/write lock be good fro this purpose or is there another method I should be using?

Hello,
I have develop a driver for my hardware and now, I need to handle a IRQ but I does not work.
As I can understand, to handle a irq, it is necessary to make a request_irq(). If the return value is zero, ok, no problem to handle irq.
Here is a easy example of my driver:

Hi I actually wrote a simple module and I need to call a bin file from that module. Could you give me some hints how to do that?
(I tried with stdlib.h and 'system()', but cannot call that function from a module).

cannot generate .ko file on my linux, although it can generate module.symvers.
But when I copy .c file and Makefile to another linux computer, there's no problem.
The strange thing is: make is successfuly executed, and returned 0;
