Subject: Question (tty ldisc): safe to use disc_data without changing ldisc?
Date: Wed, 25 Feb 2004 15:41:03 +0100 [thread overview]
Message-ID: <403CC211.15219.1B38200@localhost> (raw)
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
