Revision fa41b900c30b45fab03783724932dc30cd46a6be authored by Kirill A. Shutemov on 22 March 2018, 23:17:31 UTC, committed by Linus Torvalds on 23 March 2018, 00:07:01 UTC
deferred_split_scan() gets called from reclaim path. Waiting for page

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.
