This test verifies that data written to a vpmem.
device persists across system reboots.
Test steps:

  1. Check for vpmem device availability
  2. Create namespace using ndctl
  3. Create file system with DAX support
  4. Mount the vpmem device with DAX option
  5. Create a test file with unique content
  6. Reboot the system
  7. Remount the vpmem device
  8. Verify the test file still exists with correct content
