# mmap test purpose

# __stc_assertion_start
#
# ID: mmap_004
#
# DESCRIPTION:
#        Verify smbfs-mmap can getpage without block i/o
#
# STRATEGY:
#       1. run "mount -F smbfs //server/public /export/mnt"
#       2. mkfile in smbfs
#	3. with discrete mmap, cp the file into local dir
#	4. diff src file and des file
# KEYWORDS:
#
# TESTABILITY: explicit
