Looks like we are adding more fit to page params to this function. Can you
create a struct with all these bool params as member variables?

Done.

 #elif defined(OS_CHROMEOS)
   // Saves the underlying data to the file associated with fd. This function
   // should ONLY be called after the metafile is closed.
