# DESCRIPTION:
# Verify aclinherit=passthrough-x will inherit the execute permission only if
# file creation mode requests it.
#
# STRATEGY:
# 1. Use both super user and non-super user to run the test case.
# 2. Set aclinherit=passthrough-x
# 3. Create basedir and a set of files, one with 644 and one with 755 mode.
# 4. Verify that execute permission is inherited only if file creation mode
#    requests them.
