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