Hey Guys, I am a few basic and perhaps stupid questions. After doing some research, why are we using a worker thread for usb drivers and the like versus softrqs for networking. I am assuming this is due to the networking stack in need of more scalability versus USB and timing demands and various things . I am also curious, not from a theoretical as I am reading Linux Kernel Development( if Robert is reading this, great job on this book :) ) and learning a lot, need to brush up some of my kernel skills as stated. Further more I am wondering when are tasklets too slow or not scalable enough and we need to move to softriqs, I am asking from experience and not theoretical as i can just Google or read my copy of LKD. Regards Nick
