Linux Kernel Programming Vs Linux Device Drivers Programming

Linux Kernel Programming	Linux Device Drivers
Kernel Developers focus on interfaces, data structures, algorithms and optimization for the core of the operating system.	Device Drivers use the interfaces and data structures written by the kernel developers to implement device control and IO.
Kernel programming is done using Module programming technique.There are no standard libraries available. Have to use pure C programming.	Device Drivers is done using Module programming technique.There are no standard libraries available. Have to use pure C programming.
A very good kernel programmer may not know a lot about interrupt latency and hardware determinism, but he will know a lot about how locks, queues and Kobjects work.	A device driver programmer will know how to use locks, queues and other kernel interfaces to get their hardware working properly and responsively, but he won’t be as likely to fix a page allocation bug or write a new scheduler.
