module usage count

module usage count

[J.Hwan Kim]

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

I don't think so.

You can do that by doing fops_get
Or module_get.
