@ -185,13 +185,13 @@ filesystem, so both st_dev and st_ino of the file may change.
Any open files referring to this inode will access the old data.
Any file locks (and leases) obtained before copy_up will not apply
to the copied up file.
If a file with multiple hard links is copied up, then this will
"break" the link. Changes will not be propagated to other names
referring to the same inode.
Directory trees are not copied up. If rename(2) is performed on a directory
which is on the lower layer or is merged, then -EXDEV will be returned.
