Log:
Upgrade Chipfancier SLC quirk to all versions
The 16GB, 32GB and 128GB versions of this product all have the same
problem. For some reason, the RC10 size is correct, while the RC16
size is larger (oddly by the capacity size / 1024 bytes). Using the
RC16 size results in illegal LBA range errors when geom tastes the
device. So, expand the quirk to cover all versions of this chip.
Ideally, we'd get both READ CAPACITY 10 and READ CAPACITY 16 sizes and
print a warnnig if they differ and use the smaller of the two numbers,
though that may be problematical as well. Furthermore, SBC-4
encourages users transition to RC16 only, which suggests that in the
future RC10 may disappear from some drives. It's unclear how to cope
with these drives generically.
