The verifier checks explicitly for bp->b_bn == XFS_SB_DADDR to match the primary superblock buffer, but the primary superblock is an uncached buffer and so bp->b_bn is always -1ULL. Hence this never matches and the CRC error reporting is wholly dependent on the mount superblock already being populated so CRC feature checks pass and allow CRC errors to be reported. Fix this so that the primary superblock CRC error reporting is not dependent on already having read the superblock into memory.

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.
