Update of /cvsroot/src/sys/kern
In directory netbsd1:/var/slash-tmp/cvs-serv29127

Modified Files:
        vfs_bio.c 
Log Message:
In bread() and breadn(): if getblk() returns a DELWRI buffer, don't
call biowait() but return `success' immediately. We can return `success'
because buffers with recorded errors are not returned by getblk().
(Takes care of PR#3694).
