<pre>commit fa41b900c30b45fab03783724932dc30cd46a6be

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.
