My patch is useless. kmem_getpages called with nodeid == -1 falls back correctly to the available node. The problem is that the node structures for the page does not exist. > But what I am really wondering about is, why wasn't the > N_NORMAL_MEMORY revert enough? I assume this used to work before so what > more do we need to revert for 2.6.24? I think that is because SLUB relaxed the requirements on having regular memory on the boot node. Now the expectation is that SLAB can do the same. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
