For the zone append emulation, the write locking is done by sd.c and the upper

UFS version of the sd write locking calls that is optimized for the device
capabilities and we can keep a common upper layer (which is preferable in my
opinion).

I see a blk_req_zone_write_trylock() call in sd_zbc_prepare_zone_append() and a blk_req_zone_write_unlock() call in sd_zbc_complete() for REQ_OP_ZONE_APPEND operations. Does this mean that the sd_zbc.c code restricts the queue depth to one per zone for REQ_OP_ZONE_APPEND operations?

Thanks,

Bart.
