There was a problem hiding this comment.
Update the comment as well? "inode" should refer to host inode or real inode?

When use_host_ino mode is turned on, we only need to save the by_id relationship if the host inode of the file is larger than MAX_HOST_INO, and don't remove it. however, the previous code used a virtual inode combining the host inode, dev, mnt, and other parts of the file, and this inode is a 56bit inode, which is always larger than MAX_HOST_INO, and so it resulted in the by_id relationship not being cleaned up.
