Good spotting! You are right, I need both bits to be set...
libata: Report zeroed read after Trim and max discard size
Our current Trim payload is a single sector that can accommodate 64 *
65535 blocks being unmapped. Report this value in the Block Limits
Maximum Unmap LBA count field.
If a storage device supports Trim and the DRAT and RZAT bits are set,
report TPRZ=1 in Read Capacity(16).

The two libata patches look good. I need to review the thread one more
time, and then will apply these...
