As Pavel Machek reported:
"We normally use -EUCLEAN to signal filesystem corruption. Plus, it is
good idea to report it to the syslog and mark filesystem as "needing
fsck" if filesystem can do that."
Still we need improve the original patch with:
- use unlikely keyword
- add message print
- return EUCLEAN
However, after rethink this patch, I don't think we should add such
condition check here as below reasons:
- We have already checked the field in f2fs_sanity_check_ckpt(),
- If there is fs corrupt or security vulnerability, there is nothing
to guarantee the field is integrated after the check, unless we do
the check before each of its use, however no filesystem does that.
- We only have similar check for bitmap, which was added due to there
is bitmap corruption happened on f2fs' runtime in product.
- There are so many key fields in SB/CP/NAT did have such check
after f2fs_sanity_check_{sb,cp,..}.
So I propose to revert this unneeded check.

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.
