gcc warns that function print_lock_trace() is unused if
CONFIG_PROVE_LOCKING isn't set.
../kernel/locking/lockdep.c:2820:13: warning: ‘print_lock_trace’ defined
but not used [-Wunused-function]
static void print_lock_trace(struct lock_trace *trace, unsigned int
spaces)
Rework so we remove the function if CONFIG_PROVE_LOCKING isn't set.
