2.5.59-mm9

. Adam's cleanup and cutdown of devfs has been put back in again.  We
  really need devfs users to test this and to report, please.  (And not just
  to me!  I'll only bounce it to Adam J.  Richter <[e-mail]>
  anyway)

  Adam has a userspace helper app `devfs-helper' at

  	ftp://ftp.yggdrasil.com/pub/dist/device_control/devfs/

. The I/O scheduler changes here are stable now.  All-round peformance is
  OK.

  I've been using it on the desktop for a week.  Certain operations are
  noticeably different; for example a big `cvs co' would previously have had
  several-second stalls every 20 seconds or so.  Now, things slow down but it
  keeps going.  I'm sure the overall runtime will be slightly increased, but
  overall the decreased read latency is good.

. dcache_rcu has been put back.
