Aaargh!  Fixing that helped a lot:

# /sbin/fstrim --listed-in /etc/fstab:/proc/self/mountinfo --verbose
/disk2: 115.6 MiB (121245696 bytes) trimmed on /dev/nvme1n1p1
/: 1.8 TiB (1983153356800 bytes) trimmed on /dev/nvme0n1p2
/boot/efi: 1017.7 MiB (1067110400 bytes) trimmed on /dev/nvme0n1p1

Thanks to everybbdy who answered my stupid question!  (And amazing that 
the system can run almost normally with a missing root fs entry in fstab.)
