Subject: [PATCH v4 0/8] extend hugepage migration
Newsgroups: gmane.linux.kernel
Date: Thursday 25th July 2013 04:54:55 UTC (over 3 years ago)
Here is the 4th version of hugepage migration patchset.
I added Reviewed/Acked tags and applied the feedbacks in the previous
discussion
(thank you, all reviewers!):
 - fixed macro (1/8)
 - improved comment and readability (1/8, 3/8, 4/8, 7/8)
 - improved node choice in allocating destination hugepage (7/8)

TODOs: (likely to be done after this work)
 - split page table lock for pmd/pud based hugepage (maybe applicable to
thp)
 - improve alloc_migrate_target (especially in node choice)
 - using page walker in check_range

I hope that this series is becoming ready to be merge to -mm tree.
Andrew, could you review and judge this?

Thanks,
Naoya Horiguchi
