Qualification:  Behaving the way XFS did a few years ago.  It was fixed
and has been for a few years now.

I've been using XFS since its problems were fixed and haven't suffered
any data loss due to it despite many unclean shutdowns due to power
loss.

I am now considering using ext4 when I upgrade to 9.10, however.
