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.
