What Information does linux driver modules (.ko )files has ?
kernel 2.6 introduces a new file naming convention: kernel modules now have a .ko extension (in place of the old .o extension) which easily distinguishes them from conventional object files. The reason for this is that they contain an additional .modinfo section that where additional information about the module is kept. Linux program modpost can be used to convert .o files into .ko files.
