From e1290b3e62c496ade19939ce036f35bb69306820 Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Fri, 20 May 2011 13:49:51 -0400 Subject: ext4: Remove unnecessary wait_event ext4_run_lazyinit_thread() For some reason we have been waiting for lazyinit thread to start in the ext4_run_lazyinit_thread() but it is not needed since it was jus unnecessary complexity, so get rid of it. We can also remove li_task and li_wait_task since it is not used anymore.
