What is meaning of value stored in /sys/block/sda/queue/max_segments (what are those segments?) ? Is it fixed value assigned to block device? Or can I change it in runtime? Where in kernel this value is set initially? Considering scsi and nvme, is it set in different places? Is it matter of driver?
