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()
