[PATCH 1/9] mm: turn migrate_vma upside down
...d cost
-and thus batching multiple pages is needed as otherwise the migration overhead
-makes the whole exercise pointless. The second reason is because the
-migration might be for a range of addresses the device is actively accessing.
-
-The migrate_vma_ops struct defines two callbacks. First one (alloc_and_copy())
-controls destination memory allocation and copy operation. Second one is there
-to allow the device driver to perform cleanup operations after migration::

- struct migrate_vma_ops {
- void (*alloc_and_copy)(struct vm_area_struct *vma,
- const unsigned long *src,...

turn hmm migrate_vma upside down v3
Hi Jérôme, Ben and Jason,
below is a series against the hmm tree which starts revamping the
migrate_vma functionality. The prime idea is to export three slightly
lower level functions and thus avoid the need for migrate_vma_ops
callbacks.
