       The  vm_map_sync()  function forces any dirty cached pages in the range start to end within the map to be
       pushed to their underlying pager.

       If syncio is TRUE, dirty pages are written synchronously.

       If invalidate is TRUE, any cached pages are also freed.

       The range provided must be contiguous, it MUST NOT contain holes.  The range provided  MUST  NOT  contain
       any sub-map entries.

       The vm_map_sync() function returns KERN_SUCCESS if successful.

       Otherwise,   KERN_INVALID_ADDRESS  will  be  returned  if  the  function  encountered  a  sub-map  entry;
       KERN_INVALID_ARGUMENT will be returned if the function encountered a hole in the region provided,  or  if
       an entry could not be found for the given start address.
