I updated patches for supporting move charge of file pages.
I changed the meaning of bit 1 and 2 of move_charge_at_immigrate: file pages
including tmpfs can be moved by setting bit 1 of move_charge_at_immigrate
regardless of the mapcount, and I don't use bit 2 anymore.
And I added a clean up patch based on KAMEZAWA-san's one.
[1/2] memcg: clean up move charge
[2/2] memcg: move charge of file pages
ChangeLog:
- v2->v3
- based on mmotm-2010-04-05-16-09.
- added clean up for is_target_pte_for_mc().
- changed the meaning of bit 1 and 2. charges of file pages including tmpfs can
be moved regardless of the mapcount by setting bit 1 of move_charge_at_immigrate.
- v1->v2
- updated documentation.
Thanks,
Daisuke Nishimura.
