In this sentence, "generally" probably means "typically", so it depends
on the specific file system's behavior. I don't know the CephFS behavior
in this case. However, at least files created with O_TMPFILE are an
exception. Does CephFS support creating files with O_TMPFILE? Such files
can (and often will) go from the unlinked and open state to the linked
and closed state.
