I think we are talking cross purposes. default_dram_type = mt_find_alloc_memory_type(MEMTIER_ADISTANCE_DRAM, &default_memory_types); Is what I was suggesting. > > > > if (IS_ERR(default_dram_type)) > > > panic("%s() failed to allocate default DRAM tier\n", __func__); > > > > > > @@ -868,6 +921,14 @@ static int __init memory_tier_init(void) > > > * types assigned. > > > */ > > > for_each_node_state(node, N_MEMORY) { > > > + if (!node_state(node, N_CPU)) > > > + /* > > > + * Defer memory tier initialization on CPUless numa nodes. > > > + * These will be initialized after firmware and devices are > > > > I think this wraps at just over 80 chars.

I wonder if you have a different tab indent size? The kernel uses 8 characters. It might explain the few other odd indents if perhaps you have it at 4 in your editor? https://www.kernel.org/doc/html/v4.10/process/coding-style.html Jonathan > > > > + * initialized. > > > + */ > > > + continue; > > > + > > > memtier = set_node_memory_tier(node); > > > if (IS_ERR(memtier)) > > > /* > > > >
