Ok, with your patches applied and CONFIG_SLAB enabled:
MemTotal: 8264640 kB
MemFree: 7119680 kB
Slab: 207232 kB
SReclaimable: 32896 kB
SUnreclaim: 174336 kB
For reference, same kernel with CONFIG_SLUB:
MemTotal: 8264640 kB
MemFree: 4264000 kB
Slab: 3065408 kB
SReclaimable: 104704 kB
SUnreclaim: 2960704 kB
So CONFIG_SLAB is much better in this case.
Without your patches (but still CONFIG_HAVE_MEMORYLESS_NODES, kthread
locality patch and two other unrelated bugfix patches):
3.13.0-slub:
MemTotal: 8264704 kB
MemFree: 4404288 kB
Slab: 2963648 kB
SReclaimable: 106816 kB
SUnreclaim: 2856832 kB
3.13.0-slab:
MemTotal: 8264640 kB
MemFree: 7263168 kB
Slab: 206144 kB
SReclaimable: 32576 kB
SUnreclaim: 173568 kB
In case it's helpful, I've attached /proc/slabinfo from both kernels.
Thanks,
Nish
