. 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.

Hi,

LVM or device mapper seems to be broken in -mm. I've only tried the 
following kernels so far: 
2.5.64 - works 
2.5.65-mm2 - doesn't work 
2.5.66 - works 
2.5.66-mm1 - doesn't work

Just another data point. LVM in -mm stopped working for me at
2.5.65-mm2, it did work in 2.5.65-mm1. 2.5.65-mm[234] did not work
either.

Regards,

Shane

    Isn't it still horribly broken ? I remember Al putting it on
    the "To be fixed later" burner, but never saw anything happen
    to it after that asides from janitor style fixes.

Yes, umsdos is victim of bitrot.
Al broke it with his patch called MA37-break-umsdos-C3-pre3.
Afterwards people doing global changes failed to do them on
umsdos, so the amount of work required to get umsdos in the
shape it was before (working, but with races and other problems)
increases in time.

I failed to cc the list on the patch referred to above.
It is rather useless since umsdos is broken, but at least
prevents increased bitrot. Let me include it here.
