2.5.65-mm4

[Andrew Morton <akpm@digeo.com>]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.65/2.5.65-mm4/

. Anyone who was having problems with knfsd exports should find them fixed
  here.  It was a 32-bit dev_t problem.

. Several ext3 speedups here.  They reduce the overhead of a write() to
  ext3 by about 45%.

. Large locking changes to ext3.  lock_kernel() has been completely
  removed from ext3 and pushed down into the JBD layer, around those bits
  which actually need it.

  Lock contention is greatly reduced, but this change means that the
  front-line locking for ext3 is now two semaphores.  The context switch rate
  under load has gone through the roof.  So there is more work to be done
  here yet.

. Managed to reduce the number of patches from 127 down to 74 by various
  means.  The major outstanding things here at present are the anticipatory
  scheduler, object-based-rmap and ext3 locking work.
