The summary for this patch should probably be changed, yes? It should happen
with filesystems other than ext4 that use barriers (i.e., btrfs, XFS), and it
should happen on a single disk just as easily as a LVM. The latter I can
confirm --- you can see the performance degradation quite easily on a single
disk, so the mention of LVM in the summary is probably misleading.
