Subject: [PATCH v5 0/9] extend hugepage migration
Newsgroups: gmane.linux.kernel
Date: Friday 9th August 2013 05:21:33 UTC (over 3 years ago)
Here is the 5th version of hugepage migration patchset.
Changes in this version are as follows:
 - removed putback_active_hugepages() as a cleanup (1/9)
 - added code to check movability of a given hugepage (8/9)
 - set GFP MOVABLE flag depending on the movability of hugepage (9/9).

I feel that 8/9 and 9/9 contain some new things, so need reviews on them.

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

Thanks,
Naoya Horiguchi
