Subject: commited B_RELBUF/B_DELWRI fix from -current into -stable in brelse()
Sender: owner-cvs-all@FreeBSD.ORG
Precedence: bulk

    I've been running this patch on BEST's -stable machines for 
    over a month now with no detriment.  I've commited it into
    -stable.  The patch fixes the lost file write data VM problem
    where modified data pages would sometimes not get committed to
    disk and the page would then be freed/reused, causing the write
    to be lost.

    As more and more programs use mmap(), I consider it critical 
    that we fix mmap() (and the VM system in general).  We seem to
    be very close, if not already there in -current!
