From ec79d6056de58511d8e46d9ae59d3878f958dc3e Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 1 Jun 2010 22:53:01 +0200 Subject: tty: replace BKL with a new tty_lock As a preparation for replacing the big kernel lock in the TTY layer, wrap all the callers in new macros tty_lock, tty_lock_nested and tty_unlock.
