In mm/slab.c, change the #define value of SLAB_BREAK_GFP_ORDER from
2 to 1. This will give a page-order of 1 for the 2048 and 4096 caches.
If you want an order of zero then set SLAB_BREAK_GFP_ORDER to 0, and
SLAB_MIN_OBJS_PER_SLAB to 1.
Alexey, please play with these values as Mark describes and see if
they make some difference in the problems you told me about.
