    kernel - TMPFS - Stabilization pass, fix VM object leak, msync
    
    * The swap vm_object backing regular files was not being deallocated
      properly and leaked kernel memory.
    
    * Truncate deleted files a little earlier in the INACTIVE path.
    
    * Set MNTK_NOMSYNC.  This prevents msync(), sync(), and the
      periodic filesystem syncer from flushing pages to swap.
    
      VM pages related to tmpfs are only flushed based on memory
      pressure.
