recently, I am studying Intel's Data Plane Developer Kit to search a solution for fast-path network processing, when I try the 1.4 version on a ubuntu server, at the stage of creating hugepage tlbfs, I met a problem.
when creating success, there will be file nodes under /mnt/huge/, but now I try many times, there are no nodes being created though with the same operation.
Here is my operation log, please someone give some advice, thanks!
