This behavior is consistent with the upstream OpenZFS code and the test cases depend on it. The actual implementation differs slightly due to device naming conventions on Linux. - auto_online_001_pos, auto_replace_001_pos and add-o_ashift test cases updated to expect failure when no label exists. - read_efi_label() and zpool_label_disk_check() are read-only operations and should use O_RDONLY at open time to enforce this. - zpool_label_disk() and zpool_relabel_disk() write the partition information using O_DIRECT an fsync() and page cache invalidation to ensure a consistent view of the device. - dump_label() in zdb should invalidate the page cache in order to get the authoritative label from disk.
