And I don't think the upstream kernel has that limit on kmalloc size either (at least with SLUB, not sure about SLAB).This patch was actually written as an emulation of the upstream SLUB behavior, which is exactly the same thing: on large allocations forward to __g_f_p(). See include/linux/slub_def.h's definition of kmalloc_large and kmalloc.Right. But does upstream SLAB also pass through to the page allocator the same as SLUB?
No, slab just fails, in which case you have to do your own __g_f_p call.
How about SLQB?
