Hi Damien,

I think implementing the above proposal requires splitting 'use_zone_write_lock' into two variables:
(a) One member variable that indicates whether the zone write lock
    should be used.
(b) Another member variable that indicates whether or not the LLD
    preserves the order of SCSI commands.

Member variable (b) should be set by the LLD and member variable (a) can be set by disk_set_zoned().

Do you want me to implement this approach?

Thanks,

Bart.
