Reduce high order allocations for some setups. (NR_CPUS=4096 -> we need 64KB per kmem_cache struct) We now allocate exact needed size (using nr_cpu_ids and nr_node_ids) This also makes code a bit smaller on x86_64, since some field offsets are less than the 127 limit : Before patch : # size mm/slab.o text data bss dec hex filename 22605 361665 32 384302 5dd2e mm/slab.o After patch : # size mm/slab.o text data bss dec hex filename 22349 353473 8224 384046 5dc2e mm/slab.o CC: Andrew Morton <akpm@linux-foundation.org> Reported-by: Konstantin Khlebnikov <khlebnikov@openvz.org> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: Pekka Enberg <penberg@kernel.org> |
