A Module - is just object code linked with the kernel when insmod'ed, 1) Can't be executed on their own , it is not an executable . 2) Doesn't have any struct task_struct associated with it, Since it is not a process . 3) Can be considered as a library , which processes use ( through an interface ), hence they run in process context ( not always though ).

More than what a process can do , cause your module code is executing in kernel mode. > > Thanks, > rakesh > cheers, Amith -- Kernelnewbies: Help each other learn about the Linux kernel.
