Hi,
I only have btrfs on my laptop and just started getting this.
I''m not too clear about whether it''s in memory or on my
filesystem somewhere.
Can you recommend what I should do: reboot? fsck somehow? other?

I indeed should have searched that first instead of assuming it was btrfs related. I can also confirm that rebooting made the message go away. Thanks for your answer and sorry for posting to the wrong list. Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
