This isn't right. Bytes 7 & 8 of a TRIM range request form a counter. So, a counter of 1 = (1 x max_dsm_blocks); 2 = (2 x max_dsm_blocks) up to 0xFFFF counts. And you can have 64 range requests (contiguous or disjoint) in a 512 byte DSM payload. But these are the maximum possible limits; and I don't how many `counts' would be valid in a synchronous request like yours. Start with a `count' of 1 after you set the LBA48 flag. -RVP
