Hi Ikegami,

Are you actually able to bump up the max segments with the original patch?

No as you mentioned currently it is limited by NVME_MAX_SEGS.
On the older kernel version it was not limited by the value but limited 
by USHRT_MAX.
So it was able to change the limit by the patch.

As Keith-san also mentioned currently it is limited by the 4MB and 127 
segments as you mentioned by the NVMe PCIe driver.
So I will do abandon the patch to increase max segments.
