The condition that was causing that seems to have cleared by
itself this morning before 4am.

flush-btrfs-1 and sync are still in D state.

Can't really tell what cleared it. Could be when the first of
the rsyncs ended as all the other ones (and ntfsclones from nbd
devices) ended soon after

Cheers,
Stephane
