Hi Christoph,
The linux-next tree, since the next-20230522 tag, LTP/writev07[1]
starts to fail on xfs, not on other fs. It was pass on the previous
tag next-20230519.
After those 2 commits reverted on the top of 0522 tree, it passed.
iomap: update ki_pos in iomap_file_buffered_write
iomap: assign current->backing_dev_info in iomap_file_buffered_write
(the second one was reverted because the first one depends on it)
The test case writev07 forms an iovec with a bad address in the middle,
then writes to the file, expecting a fault return and file not being written.
Now it fails with a fault return but the file has been written.
Looks like it is related to the pos update, could you help to take a look ?
Thanks,
Murphy
