[SPDK] Re: Possible to use several hugepage files for NVMe's DMA destination?

Hi Jin，

I think that your version may be old. Currently, SPDK can support huge page map with process id. If you use newer version, you can check the file names in the huge page mounted folder, each  primary process will have its own huge page file. So I think that you need to update your spdk version, e.g., spdk 20.01 LTS is recommended.
