The patch titled
kernel/lockdep.c: possible cleanups
has been removed from the -mm tree. Its filename is
lockdep-core-cleanups.patch
This patch was dropped because it was folded into lockdep-core.patch
------------------------------------------------------
Subject: kernel/lockdep.c: possible cleanups
From: Adrian Bunk <bunk@xxxxxxxxx>
- make the needlessly global variable lockdep_init_error static
- make the needlessly global lockdep_print_held_locks() static
- #if 0 the unused global print_lock_classes()
(this also implies to #if 0 some static functions)
Signed-off-by: Adrian Bunk <bunk@xxxxxxxxx>
