Hi all, Linking Module to the kernel I read the following blocks in Linux device driver third edition for linking Module ( rmmod and insmod commands ) 1) blk_init_queue 2) add_disk 3) request 4) del_gendisk i can't able to understand how the actual linking is going on. Also i read about user and kernel space as they have different memory mappings i.e. its own address space. What does it mean ? please help me in clearing all these concepts.
