Problem of workqueue

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!
