Add another layer of fallback policy to make the home node concept useful from a memory allocation PoV. This changes the mpol order to: - vma->vm_ops->get_policy [if applicable] - vma->vm_policy [if applicable] - task->mempolicy - tsk_home_node() preferred [NEW] - default_policy Note that the tsk_home_node() policy has Migrate-on-Fault enabled to facilitate efficient on-demand memory migration.
The numa hierachy is already complex. Could we avoid adding another layer by adding a MPOL_HOME_NODE and make that the default? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
