Subject: Question about fsck for ext4

Hi! We are using the k8 utils opensource project(https://github.com/kubernetes/utils) and looking for your thoughts on an issue where fsck is being run on every remount and if this is necessary for journaling filesystems.  Eric Sandeen's comments here(https://github.com/kubernetes/utils/pull/132#issuecomment-605492335) indicate it is not but wanted to verify with you that his statements apply to ext4 as well.  Ultimately I am looking for reassurance to relax the need for fsck on mounts for ext4.  I look forward to hearing your thoughts and please don't hesitate to ask clarifying questions. Thank you!
