A.1.1. Changes
between 2.4 and 2.6
I don't know the entire kernel well enough to document all of
the changes. Some hints for porting can be found by comparing this
version of the LKMPG with it's counterpart for kernel 2.4. Apart
from that, anybody who needs to port drivers from 2.4 to 2.6
kernels might want to visit https://lwn.net/Articles/driver-porting/ . If you still
can't find an example that exactly meets your needs there, find a
driver that's similar to your driver and present in both kernel
versions. File comparison tools like xxdiff
or meld can be a great help then. Also check
if your driver is covered by docs in linux/Documentation/ . Before starting with porting
and in case you're stuck it's a good idea to find an appropiate
mailinglist and ask people there for pointers.
