But, there are also little more differences between the path namespace and head namespace: cat /sys/block/nvme0n1/queue/nr_requests: 128 cat /sys/block/nvme0c0n1/queue/nr_requests: 1023
nr_request is a noop for bio-based drivers.
cat /sys/block/nvme0n1/queue/iostats: 0 cat /sys/block/nvme0c0n1/queue/iostats: 1
iostats for bio based drivers require extra code, and we don't really need those.
cat /sys/block/nvme0n1/queue/rq_affinity: 0 cat /sys/block/nvme0c0n1/queue/rq_affinity: 1
rq_affinity is a noop for bio based drivers. _______________________________________________ Linux-nvme mailing list Linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
