This patch will allow the driver to limit max_sectors as before # cat /sys/block/sdb/queue/max_sectors_kb 512 I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2 before seeing corruption, but seems safer to use previous limit. Without this patch max_sectors_kb will be 32767. tj: Minor comment update.
