commita408f33e89upstream. When online resizing is performed twice consecutively, the error message "Superblock checksum does not match superblock" is displayed for the second time. Here's the reproducer: mkfs.ext4 -F /dev/sdb 100M mount /dev/sdb /tmp/test resize2fs /dev/sdb 5G resize2fs /dev/sdb 6G To solve this issue, we moved the update of the checksum after the es->s_overhead_clusters is updated.

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.
