Wondering what to do about this error which says 'reboot needed'. Has
happened a three times in the past week:
Well, I don't think btrfs's logic here is wrong, the following stack
shows that a nfs client has sent a second unlink against the same inode
while somehow the inode was not fully deleted by the first unlink.
So it'd be good that you could add some debugging information to get us
further.
Thanks,
