SubjectQuestion (tty ldisc): safe to use disc_data without changing ldisc?
Hello experts,

I have a question: In a kernel modification I dynamically add some data
structure that is referred to by using the "disc_data" member of the tty
structure. My question is: is it safe to do that (I'm using a new magic number
of course), or can some other code just replace my reference? If it's not
safe, how would I correctly do that?

Any pointers to written (up to date) online documents are OK...

Regards
Ulrich
