As Ju Hyung reported: " I was semi-forced today to use the new kernel and test f2fs. My Ubuntu initramfs got a bit wonky and I had to boot into live CD and fix some stuffs. The live CD was using 4.15 kernel, and just mounting the f2fs partition there corrupted f2fs and my 4.19(with 5.1-rc1-4.19 f2fs-stable merged) refused to mount with "SIT is corrupted node" message. I used the latest f2fs-tools sent by Chao including "fsck.f2fs: fix to repair cp_loads blocks at correct position" It spit out 140M worth of output, but at least I didn't have to run it twice. Everything returned "Ok" in the 2nd run. The new log is at http://arter97.com/f2fs/final After fixing the image, I used my 4.19 kernel with 5.2-rc1-4.19 f2fs-stable merged and it mounted. But, I got this: [ 1.047791] F2FS-fs (nvme0n1p3): layout of large_nat_bitmap is deprecated, run fsck to repair, chksum_offset: 4092 [ 1.081307] F2FS-fs (nvme0n1p3): Found nat_bits in checkpoint [ 1.161520] F2FS-fs (nvme0n1p3): recover fsync data on readonly fs [ 1.162418] F2FS-fs (nvme0n1p3): Mounted with checkpoint version = 761c7e00 But after doing a reboot, the message is gone: [ 1.098423] F2FS-fs (nvme0n1p3): Found nat_bits in checkpoint [ 1.177771] F2FS-fs (nvme0n1p3): recover fsync data on readonly fs [ 1.178365] F2FS-fs (nvme0n1p3): Mounted with checkpoint version = 761c7eda I'm not exactly sure why the kernel detected that I'm still using the old layout on the first boot. Maybe fsck didn't fix it properly, or the check from the kernel is improper. " Although we have rebuild the old deprecated checkpoint with new layout during repair, we only repair last checkpoint park, the other old one is remained. Once the image was mounted, we will 1) sanity check layout and 2) decide which checkpoint park to use according to cp_ver. So that we will print reported message unnecessarily at step 1), to avoid it, we simply move layout check into f2fs_sanity_check_ckpt() after step 2).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
