Sure, I know they've made progress, which is why I didn't also bring up
older ugly problems like delayed allocation issues reducing files to zero
length on XFS. I thought that particular issue was pretty fundamental to
the logical journal scheme XFS is based on. What's you'll get out of disk
I/O at smaller than the block level is pretty unpredictable when there's a
failure.
