We can improve it in libmount and add any if-erofs hack there, but my

Thanks for your suggestion!
it's somewhat weird to use erofsprefix here, I think fsoffset
may be fine.
Yes, fsoffset sounds good. I anticipate more filesystems will support
file-backed mounts in the future, making this option reusable.
From my own kernel perspective, it's not possible for the majority
of read-write fses especially have nested transaction (like
`current->journal_info`) in addition to many deadlock factors
without extra workqueue contexts. But for erofs it's safe.
Thanks,
