Hi, friends:

I am reading VM source code concerning the vm_map_entry structure.  There
is a flag called MAP_ENTRY_IS_A_MAP used widely, but I search all the
codes in VM and can not find where this flag gets set into the eflags
field of the vm_map_entry structure.  By the way, MAP_ENTRY_IS_A_SUB_MAP
is set in vm_map_submap( ).  It is often used together with
MAP_ENTRY_IS_A_MAP.  I hope someone can give me a hint on this.

Thanks a lot.
