Andrea Arcangeli 99a1300e1d thp: avoid VM_BUG_ON page_count(page) false positives in __collapse_huge_page_copy ... Speculative cache pagecache lookups can elevate the refcount from under us, so avoid the false positive. If the refcount is < 2 we'll be notified by a VM_BUG_ON in put_page_testzero as there are two put_page(src_page) in a row before returning from this function.
