Sounds like a reference counting problem.
As far as I know, reference counter for line discipline sets to 0 in tty_register_ldisc(),
Not for the discipline, for the *MODULE*.
And please advice how could I transfer data between kernel and user space not using filp_open() and filp_close().
Depends on the data. sysfs, netlink, debugfs, or having userspace open the file and using that, or any number of other ways to do it.
