03ef80b469d5d83530ce1ce15be78a40e5300f9b is the first bad commit
commit 03ef80b469d5d83530ce1ce15be78a40e5300f9b

    bcachefs: Ignore unknown mount options
    
    This makes mount option handling consistent with other filesystems -
    options may be handled at different layers, so an option we don't know
    about might not be intended for us.
