Hi,
btrfs-progs 4.16, kernel 4.16
--mode original comes up with no errors, --mode lowmem comes up with a
bunch of "referencer count mismatch" messages and also ERROR: errors
found in extent allocation tree or chunk allocation, and most of the
byte totals differ as well.

A btrfs-image for this same file system was submitted for other lowmem
complaints including this one, but seems there are more of this
message now with 4.16, and no other messages. But I can make another
image if that's helpful or whatever other info is needed.
File system is working fine near as I can tell, and passed an online
scrub in the past week with zero errors.
