commit e81c9302a6 upstream.
When migrating to extents, the temporary inode will have it's own checksum
seed. This means that, when swapping the inodes data, the inode checksums
will be incorrect.
This can be fixed by recalculating the extents checksums again. Or simply
by copying the seed into the temporary inode.

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.
