mm: use memalloc_nofs_save() in page_cache_ra_order()
Summary
In the Linux kernel, the following vulnerability has been resolved: mm: use memalloc_nofs_save() in page_cache_ra_order() See commit f2c817bed58d ("mm: use memalloc_nofs_save in readahead path"), ensure that page_cache_ra_order() do not attempt to reclaim file-backed pages too, or it leads to a deadlock, found issue when test ext4 large folio.
