The fixes have no ordering dependencies and can be applied or backported independently. Each issue was reproduced before and after its respective fix. Andrea Parri (3): iomap: don't resubmit an ioend after ->writeback_submit() failed iomap: don't lose a fiemap iteration error when emitting the last extent iomap: don't lose a failed direct I/O bio's error when zeroing the tail fs/iomap/direct-io.c | 11 ++++++++--- fs/iomap/fiemap.c | 8 ++++---- fs/iomap/ioend.c | 10 +++++++++- 3 files changed, 21 insertions(+), 8 deletions(-) base-commit: 93f51579e7df248780214094418f205253383cc5 -- 2.53.0
