Hi,
here's a separate fix that depends on changes that landed last week (the
iomap + iov_iter merged as c03098d4b9ad).
The fix itself is for a deadlock when direct/buffered IO is done on a
mmaped file and a fault happens (details in the patch). There's a fstest
generic/647 that triggers the problem and makes testing hard.
No merge conflicts. Please pull, thanks.
