Hi Nikolay,
Updating to 4.15 seems to have fixed it.
Thanks!

Hello!
I am getting ENOSPC on my root filesystem with plenty of unallocated
space according to "fi usage". Any idea why that may be? This is a root
partition for Debian Stable. Not doing anything unusual that I'm aware
of. No snapshots.
Thanks!

You haven't shown "btrfs fi usage". In any case there were some patches
in more recent kernels which deal with premature ENOSPC:
996478ca9c46 ("btrfs: change how we decide to commit transactions during
flushing")
17024ad0a0fd ("Btrfs: fix early ENOSPC due to delalloc")
I'd advise you update to 4.14 stable. Otherwise running:
git log --oneline --grep "enospc" fs/btrfs/
will shows you likely candidates.
