Do you want me to Long> send another patch with these details? no_write_same prevents us from attempting to use WRITE SAME(10/16) to zero block ranges. This is completely orthogonal to using the WRITE SAME(10/16) commands with the UNMAP bit set to discard block ranges. The latter is controlled by the logical block provisioning heuristics and is not affected by no_write_same at all. -- Martin K.
