Hi Chetan,
Thanks for reply and it works. And I want to verify some other things.
Is it a good way to use workqueue to do this job: send data to user space through netlink socket from kernel?
Thanks!

Hi,
I want to use workqueue in my irq handler. Some materials say that I can use
INIT_WORK( &work, function, &data );
to initialize work, whose type is struct work_struct, and data is something should be passed to function. however, it seems that now the macro INIT_WORK() only accept two parameters:&work and function.
My problem is how to pass data to the function and why they change that macro?
Thanks!
May be you are looking for something like this:

Hi, To send data from kernel space and user-space see kernel's notification mechanism like fanotify which works on by creating an anonymous fd in the user-space process's context which then might perform normal read() and write() call to receive and send data to kernel. - Rohan
