    mm/thp: do not wait for lock_page() in deferred_split_scan()

    deferred_split_scan() gets called from reclaim path.  Waiting for page
    lock may lead to deadlock there.

    Replace lock_page() with trylock_page() and skip the page if we failed
    to lock it.  We will get to the page on the next scan.
