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 don't think so.
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
You can do that by doing fops_get Or module_get.
