	  2 parts to this patch.
	  The first part is making buffer.c aware of delay buffers, this allows us to remove BH_Uptodate 
	  from linvfs_get_block_core.
	  The second part is a fix to end_buffer_io_async; it was checking all the buffer heads on a page
	  but not if they were uptodate or not, and therefore incorrectly setting the page uptodate.
	  Stale data was then exposed on portions of page not correctly cleared because only part of the 
	  page was actually valid.
