Upstream commit is e34438c903b6("f2fs: fix to do sanity check with node footer and iblocks"). This commit is not present in our kernels. Marking as Wontfix as CONFIG_F2FS_FS is not set.

+gwendal who is considering to use F2FS for Chrome OS
Kindly update the bug/let me know if F2FS is going to be introduced into ChromeOS. There are commits from earlier this year as well which would need to be pulled in.
