I originally looked for the same pattern elsewhere in\nour code, but mistakenly skipped over this code because I saw the page\ncache readahead before we set_page_extent_mapped, not realizing that\nthis was only in the !page case, that we can still end up with a\n!uptodate page and then do the btrfs_read_folio further down.\n\nThe fix here is the same as the above mentioned patch, move the\nset_page_extent_mapped call to after the btrfs_read_folio() block to\nmake sure that we have the subpage blocksize stuff setup properly before\nusing the page."
