2.5.56-mm1

[Andrew Morton <akpm@digeo.com>]

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.56/2.5.56-mm1/

Nothing much new here except for a fix for the ext3-related memory leak which
Con reported recently.


The main items which remain unmerged from the -mm patch series are now:

- red/black-tree based insertion and sorting for the I/O scheduler.

  Jens will be submitting this next week.  It's completely stable, and the
  patch includes the addition of the I/O scheduler tunables in
  /sys/block/hda/iosched/, which is fairly important.

- Code to automatically unplug request queues on the basis of their
  occupancy and a timeout.

  Jens will be reviewing this soon.

- dcache-RCU.

  This was recently updated to fix a rename race.  It's quite stable.  I'm
  not sure where we stand wrt merging it now.  Al seems to have disappeared.

- Ingo Oeser's user page walking rework.  This appears to be stable,
  although I'm not sure what testing it has had apart from a lot of direct-io
  testing.

- Quite a lot of misc stuff which I need to go through and either send or
  toss.
