Merge tag 'folio-5.18f' of git://git.infradead.org/users/willy/pagecache
Pull folio fixes from Matthew Wilcox:
"Two folio fixes for 5.18.
Darrick and Brian have done amazing work debugging the race I created
in the folio BIO iterator. The readahead problem was deterministic, so
easy to fix.
- Fix a race when we were calling folio_next() in the BIO folio iter
without holding a reference, meaning the folio could be split or
freed, and we'd jump to the next page instead of the intended next
folio.
- Fix readahead creating single-page folios instead of the intended
large folios when doing reads that are not a power of two in size"
