Hi Andrea,

Sorry, I should be noticed and address the issue with scan before...

Patchset below should address your concern.

I've tested it in qemu with fake numa.

Kirill A. Shutemov (3):
  thp: make split_queue per-node
  thp: change deferred_split_count() to return number of THP in queue
  thp: limit number of object to scan on deferred_split_scan()
