When target_nid is invalid\n(including the scheme default NUMA_NO_NODE / -1), damon_migrate_pages()\nreturns early without putting the folios back to the LRU.\n\nCallers then discard the list head while those folios remain isolated with\nan extra reference taken by folio_isolate_lru().  The pages stay off the\nLRU for as long as the mapping exists (anon active+inactive counts drop\nwhile RSS does not), and the leftover references can pin the pages after\nthe mapping is gone.\n\nPut the folios back on the invalid-nid path so ignored migration requests\nstill return them to the LRU."
