Modified files:
sys/vm vm_mmap.c
Log:
Use MAP_NOSYNC for vnodes without any links in their filesystem.
This is necessary for vmware: it does not use an anonymous mmap for
the memory of the virtual system. In stead it creates a temp file an
unlinks it. For a 50 MB file, this results in a ot of syncing
every 30 seconds.
