Subject: [GIT PULL] Btrfs update, part 2
Date: Wed, 10 Nov 2021 18:38:09 +0100 [thread overview]
Message-ID: <cover.1636564333.git.dsterba@suse.com> (raw)
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.
