Re: [PATCH] tree/tiny rcu: Add debug RCU head option (v2)

[Christoph Lameter]

SLAB overloads "struct slab" with the rcu_head. Its not that critical
there since the metadata allocated for each slab page is larger. SLUB does
not have such a per slab page metadata structure and limits its metadata
to what is available in the page struct.
