  30 # DESCRIPTION:
  31 # Copy a large number of files between 2 directories
  32 # within a zfs filesystem works without errors.
  33 # This make sure zap upgrading and expanding works.
  34 #
  35 # STRATEGY:
  36 #
  37 # 1. Create NR_FILES files in directory src
  38 # 2. Check the number of files is correct
  39 # 3. Copy files from src to dst in readdir order
  40 # 4. Check the number of files is correct
