Although I have no plan to learn wireless architecture, I do think that Linux kernel (device driver module) programming is not newbie-friendly. In my opinion, LDD3 is somehow outdated. Wireless network is not covered, while there is a full chapter covering parallel port, which is hard for newbies to learn due to difficulty to buy appropriate hardware. Moreover, many interfaces are updated. Semaphores have been replaced by mutexes long ago. There are also advanced .{read|write}_iter functions in file_operations which can replace {.read|.write}. I cannot understand the read_iter_zero function in drivers/char/mem.c after I read LDD3. I wish a better resource for newbies to learn driver programming, maybe LDD4, maybe a more detailed book elsewhere.
