1616 slub_debug [MM, SLUB]
1617 Enabling slub_debug allows one to determine the culprit
1618 if slab objects become corrupted. Enabling slub_debug
1619 creates guard zones around objects and poisons objects
1620 when not in use. Also tracks the last alloc / free.
1621 For more information see Documentation/vm/slub.txt.

1623 slub_max_order= [MM, SLUB]
1624 Determines the maximum allowed order for slabs. Setting
1625 this too high may cause fragmentation.
1626 For more information see Documentation/vm/slub.txt.
1627
1628 slub_min_objects= [MM, SLUB]
1629 The minimum objects per slab. SLUB will increase the
1630 slab order up to slub_max_order to generate a
1631 sufficiently big slab to satisfy the number of objects.
1632 The higher the number of objects the smaller the overhead
1633 of tracking slabs.
