ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.62/2.5.62-mm2/

Various little bits and pieces.  Mainly work against the anticipatory
scheduler.

The anticipatory scheduler has been moved into its own file now, and
deadline-iosched is unaltered from 2.5.62 base (apart from a small bugfix).

So this tree has three elevators (apart from the no-op elevator).  You can
select between them via the kernel boot commandline:

	elevator=as
	elevator=cfq
	elevator=deadline

The default is AS.

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.62/2.5.62-mm3/


. Included Dave McCracken's "Object-based RMAP" patch.

  What this dopey name actually means is that when page reclaim tries to
  unmap a file-backed page it walks the VMAs attached to the address_space
  and the pagetables attached thereto.  So there is no need for pte_chains
  for these pages.

  The patch is simple, but potentially has search complexity problems with
  weird workloads which have high sharing levels.  Allegedly.  Work is
  ongoing.

. Several more anticipatory scheduler tweaks.  This has been an exercise
  in hunting down situations in which the scheduler does the wrong thing, and
  plugging those up.

  The only known problem at this time is a ~20% falloff in threaded
  OLTP-style database activity.  This is really complex, involving
  interactions between reads, O_SYNC writes and i_sem contention.

  The problem will recede to less than 10% when we retune the anticipation
  timer (it is currently set too high just so we can discover these things). 

  But we do not see a sane way of fixing this for real.  At present it will
  need to be manually tuned away with

	echo 0 > /sys/block/hdXX/antic_expire

  Later, we will probably have to perform this disabling automatically.

. There are some performance fixes which will help OLTP-style workloads
  which are using regular old files through the pagecache.  It seems to be
  running maybe 60-70% faster than 2.4.x now, but it varies.

. A few performance patches to reduce the amount of work we do in
  update_atime() and __mark_inode_dirty() should pull back some of the
  regressions which have been observed in there.

2.5.63-mm2
From: Andrew Morton (akpm@digeo.com)
Date: Sun Mar 02 2003 - 21:09:59 EST 


http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.63/2.5.63-mm2/ 


Mainly bugfixes, and solidification of the anticipatory scheduler. 


The anticipatory scheduler has become significantly better - I believe that 
all of the little regressions which had previously been identified are fixed 
up now, with the exception of the OLTP-style database workload which is still 
10% slower. Write-versus-write latency problems have been fixed, which is 
important for ext3 behaviour during heavy writeback. 


All the infrastructure for per-task IO pattern tracking is in now place so we 
should be able to fix the OLTP slowdown without any requirement for manual 
tuning. 


We still have not located Ed Tomlinson's lost IO request. It's odd. 




If you see this come out: 


Slab corruption: start=cde0414c, expend=cde0418b, problemat=cde04162

2.5.64-mm1
From: Andrew Morton (akpm@digeo.com)
Date: Thu Mar 06 2003 - 02:07:12 EST 


http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.64/2.5.64-mm1/ 


. Included Ingo's file-offset-in-pte patch which allows pages which are in 
  nonlinear mappings to be reestablished by the kernel's pagefault handler. 
  This is enabled against all mappings for testing purposes. 


. No functional changes to the anticipatory scheduler this time. Just 
  stabilisation work. It doesn't seem to oops any more. 


. A bunch of buxfixes plus the usual sweepings off the factory floor.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO v IBM.
