K 10 svn:author V 2 dg K 8 svn:date V 27 1996-06-30T05:23:41.000000Z K 7 svn:log V 349 Brought in fix from rev 1.94: make sure pages involved in I/O are not mapped into any processes. Also set b_pages[]=0 when the pages are removed from the buffer - this is to satisfy my paranoia by making sure that nothing bogusly messes with the pages after the buffer has been reclaimed. A similar change was made in the main branch some time ago. END
