Hi there,
3rd stage of my fight with the kernel.
Problem: I have a char device which has to use information of a kernel variable (created for me) called bitmapped, this variable has to be used by the kernel to get information from user, I have thought about defining this variable in a header file for including it in the kernel, but...if my driver has to use it, can I define this variable in the code of my driver as extern if it's only defined at memory.c, for example?
Which is the best way for defining this variable at the kernel and use it from either the kernel or the user?
