| |
In Alessandro Rubini's book Linux Device Driver(Second Edition), Chatper 12, he said that "By accessing the fields in the request structure, usually by way of CURRENT" and "CURRENT is just a pointer into blk_dev[MAJOR_NR].request_queue". I know CURRENT is just a macro. Where can I find the definition of this macro? I just don't know how to get the struct request from the request_queue(a request_queue_t struct). CURRENT points to which field in the blk_dev[MAJOR_NR].request_queue? Thank you very much.
Michael
