  35 # DESCRIPTION:
  36 # When set property exec=off on a filesystem, processes can not be executed from
  37 # this filesystem.
  38 #
  39 # STRATEGY:
  40 # 1. Create pool and file system.
  41 # 2. Copy '/usr/bin/ls' to the ZFS file system.
  42 # 3. Setting exec=off on this file system.
  43 # 4. Make sure '/usr/bin/ls' can not work in this ZFS file system.
  44 # 5. Make sure mmap which is using the PROT_EXEC calls failed.
