  22 # DESCRIPTION:
  23 # Ensure both truncate(2)/ftruncate(2) update target file mtime/ctime attributes
  24 #
  25 # STRATEGY:
  26 # 1. Create a file
  27 # 2. Truncate the file
  28 # 3. Verify both mtime/ctime are updated
  29 # 4. Rinse and repeat for both truncate(2) and ftruncate(2) with various sizes
