In slab, all __xxx_track_caller is defined on CONFIG_DEBUG_SLAB || CONFIG_TRACING,
thus caller tracking function should be worked for CONFIG_TRACING. But if
CONFIG_DEBUG_SLAB is not set, include/linux/slab.h will define xxx_track_caller to
__xxx() without consideration of CONFIG_TRACING. This will break the caller tracking
behaviour then.
