- fields when not using (v6.1)

-    mm/slab_common: drop kmem_alloc & avoid dereferencing fields when not using
-
-    Drop kmem_alloc event class, and define kmalloc and kmem_cache_alloc
-    using TRACE_EVENT() macro.
-
-    And then this patch does:
-       - Do not pass pointer to struct kmem_cache to trace_kmalloc.
-         gfp flag is enough to know if it's accounted or not.
-       - Avoid dereferencing s->object_size and s->size when not using kmem_cache_alloc event.
-       - Avoid dereferencing s->name in when not using kmem_cache_free event.
-       - Adjust s->size to SLOB_UNITS(s->size) * SLOB_UNIT in SLOB
-
