Excellent, and thanks for testing!

OK, so the patches from upstream have broken f2fs support for
you. Looking at the patches, I'm not seeing anything *obvious* there
that might be an issue. They're all trying to add checks to avoid
crashes with an invalid/corrupt f2fs filesystem.

Silly question: does your filesystem have errors? Does fsck.f2fs
report anything?
