From ac751efa6a0d70f2c9daef5c7e3a92270f5c2dff Mon Sep 17 00:00:00 2001 From: Torben Hohn Date: Tue, 25 Jan 2011 15:07:35 -0800 Subject: console: rename acquire/release_console_sem() to console_lock/unlock() The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.
