module usage count
Hi, everyone When I use /proc file system in communicating between kernel and user space, is the usage count of moudule automatically incremented or decremented? I register proc file via create_proc_entry() and use .open, .close and .mmap not using .read and .write function. Please give me any hint.. Thanks in advance Best Regards, J.Hwan Kim ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
