I found some articles (like https://bbs.archlinux.org/viewtopic.php?id=75152) on the Internet saying that the default journal mode is writeback. Is that correct?
And is the journal mode of the following device writeback too? Thanks.

[root at localhost tmp]# tune2fs -l /dev/sda1
Default mount options:    user_xattr acl
