# mmap test purpose

# __stc_assertion_start
#
# ID: mmap_008
#
# DESCRIPTION:
#        Verify smbfs will keep the SMB FID alive when
#	 there are mapped pages associated with it.
#
# STRATEGY:
#       1. run "mount -F smbfs //server/public /export/mnt"
#       2. mkfile in smbfs
#	3. open, mmap & close the file, then write data into the mapped addr
#	4. verify the data successfully written back to smb server
# KEYWORDS:
#
# TESTABILITY: explicit
