51 Page migration allows the preservation of the relative location of pages

55 Processes will run with similar performance after migration.
57 Page migration occurs in several steps. First a high level

90 is increased so that the page cannot be freed while page migration occurs.
101 4. All the page table references to the page are converted to migration

148 Non-LRU page migration
151 Although original migration aimed for reducing the latency of memory access
158 For virtio-balloon pages, some parts of migration code path have been hooked
159 up and added virtio-balloon specific functions to intercept migration logics.
161 movable would have to add own specific hooks in migration path.
163 To overclome the problem, VM supports non-LRU page migration which provides
165 migration path.
189    can return -EAGAIN. On -EAGAIN, VM will retry page migration in a short time
190    because VM interprets -EAGAIN as "temporal migration failure". On returning
191    any error except -EAGAIN, VM will give up the page migration without retrying
198    If migration fails on isolated page, VM should return the isolated page
199    to the driver so VM calls driver's putback_page with migration failed page.
