  Stress testing for perfromance is being done in preparation for the the Tencent PoC Sort Competition using the attached per scripts.  The system either hangs, or the NVMe goes offline after 12 hours or so.
  The nvme drives are set up in a RAID 0 config.  The script is run like this:

  ./perf_nvme_fio2.sh nvme_jobfile_raid0_huawei

  Hi, 

  We need to apply the following patch to the Ubuntu kernel to prevent
  wrongly identification of ATARI partitions, as mentioned in the commit
  log.

  It still didn't make to Linus tree, but Jens Axboe already approved it
  on linux-block.

  block.git/commit/?h=for-4.8/core
