Description Marek Suchánek 2019-04-03 11:52:03 UTC

RHEL 8 adds support for metadata checksums in ext4. We need to prepare a release note to announce the news.

The feature is described here:

Apurva, I'm reassigning this release note to you because Ioanna told me that you have free capacity. Let me know if there's a problem with that. Thanks!
