[PATCH v2 2/5] mm/migrate: add a direction parameter to migrate_vma
...already
in NUMA zone X" if the MIGRATE_VMA_SELECT_SYSTEM flag is set.
Also, in support of the flags field, I'm looking at THP migration and I can
picture defining some request flags like hmm_range_fault() to say "migrate
THPs if they exist, otherwise split THPs".
A default_flags MIGRATE_PFN_REQ_FAULT would be useful if the source page is
swapped out. Currently, migrate_vma_setup() just skips these pages without
any indication to the caller why the page isn't being migrated or if retrying
is worth attempting.
