From 849d20a12822cba355c054ab0bfe490473413cce Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Fri, 8 Aug 2014 14:21:31 -0700 Subject: proc: remove proc_tty_ldisc variable /proc/tty/ldisc appear to be unused as a directory and it had been always that way. But it is userspace visible thing. Cowardly remove only in-kernel variable holding it.
