jbd2: If a journal checksum error is detected, propagate the error to ext4
If a journal checksum error is detected, the ext4 filesystem will call ext4_error(), and the mount will either continue, become a read-only mount, or cause a kernel panic based on the superblock flags indicating the user's preference of what to do in case of filesystem corruption being detected.
