Hi Kernelnewbies,
Please suggest me a good tutorial for learning basic kernel
programming stuff. Basics such as :
(1) Sending data from kernel => user land
(2) How to trace function calls in kernel ?
This should help:
http://en.tldp.org/LDP/khg/HyperNews/get/khg.html
there are apis like copy_to_user and copy_from_user, refer ldd or google it.
then strace can give u trace of all calls.
there are some more ways: please read Robert love or inside kernel/Documentation directory few methods are listed

People ask the question... what's a RocknRolla? And I tell 'em - it's not about drums, drugs, and hospital drips, oh no. There's more there than that, my friend. We all like a bit of the good life - some the money, some the drugs, other the sex game, the glamour, or the fame. But a RocknRolla, oh, he's different. Why? Because a real RocknRolla wants the fucking lot.
