--- Comment #3 from Chao Yu (chao@kernel.org) ---
Steve,
I figure out that patch to solve issue which I encounter with image attached by
Wen Xu, the bug can be triggered with below scripts:
- mount image /mnt/f2fs/
- cd /mnt/f2fs/foo/bar/
- ls -l
After applying that patch, the problem was gone.
But when the bug triggeres, related call stack is not the same as reported one,
also I can't reproduce reported call stack with the method provided from Wen
Xu.
I guess the right producing way is adding master key for encrypted file, I'd
like to confirm with Wen Xu.
