You almost always want to have "lazytime" behaviour though. https://lwn.net/Articles/621046/ Unfortunately it is not yet the default.
Very interesting setting. I take it tha Leap 42.2 has it, although not the default? At the time of the article, only ext4 supported it, has this changed? Supposedly it should go into the VFS.
I've tried, and the option lazytime is accepted by other partition types: reiserfs, xfs... I don't know if it is working, but it is accepted:
It is implemented in VFS layer and should be transparent to filesystem (ext4 has some explicit code, not sure whether this is leftover) as long as your mount binary understands this option and translates it into proper mount flag. Support was added in version 2.27 of util-linux.
