Subject: ext4 issue on linux-next(next-20251030)
Hi Jack,
On the latest linux-next, I find your patch acf943e9768e ("ext4: fix checks for orphan inodes") trigger the following issue on our imx7d-sdb board.
I do not have enough background knowledge of ext4, so don't know why there are orphan inodes on the partition with ext4. Not sure whether this
is a real issue or we need some special operation on current ext4 partition.
Do you have any suggestions to debug this issue?
