. The anticipatory scheduler is in wrapup mode now.  It is pretty much in
  its final form.

. The ext2 locking changes have been significantly redone.

  The per-blockgroup data structures had to go.  For a 4TB filesystem we
  cannot even kmalloc that many pointers, let alone data structures.

  So the per-blockgroup spinlocking has been replaced with hashed
  spinlocking and the per-blockgroup accounting has been removed.  A "per-cpu
  counter" thing has been invented to amortise the locking cost of the
  filesystem-wide counters.

. ext3 is now using spinlocking in its block allocator rather than a
  filesystem-wide semaphore.

  It is stability-tested but I have not yet performance tested this
  closely.  It does appear to have improved the context switch problem (and
  the file fragmentation problem which the context switch problem causes). 
  But there's a way to go here.
