Alistair Popple 00fa15e0d5 filemap: Fix serialization adding transparent huge pages to page cache ... Commit 793917d997 ("mm/readahead: Add large folio readahead") introduced support for using large folios for filebacked pages if the filesystem supports it. page_cache_ra_order() was introduced to allocate and add these large folios to the page cache. However adding pages to the page cache should be serialized against truncation and hole punching by taking invalidate_lock. Not doing so can lead to data races resulting in stale data getting added to the page cache and marked up-to-date. See commit 730633f0b7 ("mm: Protect operations adding pages to page cache with invalidate_lock") for more details. This issue was found by inspection but a testcase revealed it was possible to observe in practice on XFS. Fix this by taking invalidate_lock in page_cache_ra_order(), to mirror what is done for the non-thp case in page_cache_ra_unbounded().
