In the code comments above the WARN, this condition indicates "the

needs this set if your driver also sets the max_discard_sectors limit.
The usb-storage and uas drivers do not set any of these; however, the
SCSI sd driver does. Maybe that's where the problem lies. Adding more
CC's.
Hi,
that seems to be conditional on READ_CAPACITY_16 being used.
From the cropped dmesg we cannot tell. We need more.
