Re: [f2fs-dev] About the superblock and checkpoint
Please ignore the warning messages, maybe there are some wrong steps when testing. So sorry!

[f2fs-dev] About the superblock and checkpoint
When I make a filesystem on a disk partition (eg. /dev/sdd1), but I mount the filesystem from /dev/sdd by mistake, f2fs print the following WARNING. I don't think user want them. I have no idea to avoid or fix it? Should f2fs check both super block? or both checkpoint? Any comments are welcome.
