One of my encounters with extent corruption was probably this, but I've had other encounters with corrupt extents after this fix was applied. The most recent was summer or fall 2017 on RHEL 7.3 and deliberate because we were trying to identify a different ext4 corruption bug which turned out to be two bugs, one in ext4 and one in VFS. My recommendation not to use ext4 is less about the corruption problems, though, and more about the inability to identify and repair the damage. fsck cannot tell you what files are affected because that information is what's damaged. Since it cannot identify what's affected it cannot effect repairs, either. You have to wipe and restore from backups made prior to the corruption. -- Rich Pieri
