Hi Vlastimil, Johannes,

Could you share your view on this series when you have time?

One known issue in v2: the cc->mode != MIGRATE_ASYNC check added to
2/2 blocks clearing stale skip hints once sync compaction is fully
deferred, so local THP may not recover after the pins are released.
I'd drop it in v3, but won't send one before hearing from you.

Thanks,
Qiliang
