[PATCH] mempolicies: private pointer in check_range and MPOL_MF_INVERT
This was was first posted at
http://marc.theaimsgroup.com/?l=linux-mm&m=113149240227584&w=2
(Part of this functionality is also contained in the direct migration
pathset. The functionality here is more generic and independent of that
patchset.)
- Add internal flags MPOL_MF_INVERT to control check_range() behavior.
- Replace the pagelist passed through by check_range by a general
private pointer that may be used for other purposes.
(The following patches will use that to merge numa_maps into
mempolicy.c and to better group the page migration code in
the policy layer)
- Improve some comments.
