If the cpuset flag file 'memory_migrate' is set true, then when
tasks are attached to that cpuset, any pages that task had
allocated to it on nodes in its previous cpuset are migrated
to the tasks new cpuset. Depending on the implementation,
this migration may either be done by swapping the page out,
so that the next time the page is referenced, it will be paged
into the tasks new cpuset, usually on the node where it was
referenced, or this migration may be done by directly copying
the pages from the tasks previous cpuset to the new cpuset,

the cpuset is preserved during these migration operations if possible.
For example if the page was on the second valid node of the prior cpuset
then the page will be placed on the second valid node of the new cpuset.
Also if 'memory_migrate' is set true, then if that cpusets

will be moved to nodes in the new setting of 'mems.' Again,

Page migration allows a process to manually relocate the node on which its
pages are located through the MF_MOVE and MF_MOVE_ALL options while setting
a new memory policy. The pages of process can also be relocated

from another process using the sys_migrate_pages() function call. The
migrate_pages function call takes two sets of nodes and moves pages of a

Page migration functions are provided by the numactl package by Andi Kleen

TODO list
---------
- Page migration requires the use of swap handles to preserve the
information of the anonymous page table entries. This means that swap
space is reserved but never used. The maximum number of swap handles used
is determined by CHUNK_SIZE (see mm/mempolicy.c) per ongoing migration.
Reservation of pages could be avoided by having a special type of swap
handle that does not require swap space and that would only track the page
references. Something like that was proposed by Marcelo Tosatti in the
past (search for migration cache on lkml or linux-mm@kvack.org).
- Page migration unmaps ptes for file backed pages and requires page
faults to reestablish these ptes. This could be optimized by somehow
recording the references before migration and then reestablish them later.
However, there are several locking challenges that have to be overcome
before this is possible.
- Page migration generates read ptes for anonymous pages. Dirty page
faults are required to make the pages writable again. It may be possible
to generate a pte marked dirty if it is known that the page is dirty and
that this process has the only reference to that page.
