Currently, the XFS_SB_CRC_OFF macro uses the incore superblock struct (xfs_sb) to compute the address of sb_crc within the ondisk superblock struct (xfs_dsb). This is a landmine if we ever change the layout of the incore superblock (as we're about to do), so redefine the macro to use xfs_dsb to compute the layout of xfs_dsb. Signed-off-by: Darrick J.

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 reStructuredText 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.
