  "message": "aio/migratepages: make aio migrate pages sane\n\nThe arbitrary restriction on page counts offered by the core\nmigrate_page_move_mapping() code results in rather suspicious looking\nfiddling with page reference counts in the aio_migratepage() operation.\nTo fix this, make migrate_page_move_mapping() take an extra_count parameter\nthat allows aio to tell the code about its own reference count on the page\nbeing migrated.\n\nWhile cleaning up aio_migratepage(), make it validate that the old page\nbeing passed in is actually what aio_migratepage() expects to prevent\nmisbehaviour in the case of races.\n\nSigned-off-by: Benjamin LaHaise \u003cbcrl@kvack.org\u003e\n",
