It seems like it's a real but very rare pre-existing issue. It would require
invalidate_mapping_pages() to be called between the read_mapping_folio() and
folio_lock(), which isn't something that should happen here on any normal
workload. In any case, the fix is to check the mapping and retry if the
check fails. I'll add a patch at the start of the series fixing this for
erase and write.

Thanks,
