commit a408f33e895e455f16cf964cb5cd4979b658db7b upstream.
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.
