[PATCH *] 2.4.16-rmap-6

[Rik van Riel <riel@conectiva.com.br>]

Hi,

The 6th version of the reverse mapping based VM is now available.
This is an attempt at making a more robust and flexible VM
subsystem, while cleaning up a lot of code at the time. The patch
is available from:

	   http://surriel.com/patches/2.4/2.4.16-rmap-6
and        http://linuxvm.bkbits.net/


The big TODO items for the _next_ release are:
  - integrate some of wli's pigmem stuff
  - fix page_launder() so it doesn't submit the whole
    inactive_dirty list for writeout in one go


Changelog:

rmap 6:
  - make the active and inactive_dirty list per zone,
    this is finally possible because we can free pages
    based on their physical address                    (William Lee Irwin)
  - cleaned up William's code a bit                                   (me)
  - turn some defines into inlines and move those to
    mm_inline.h (the includes are a mess ...)                         (me)
  - improve the VM balancing a bit                                    (me)
  - add back inactive_target to /proc/meminfo                         (me)
rmap 5:
  - fixed recursive buglet, introduced by directly
    editing the patch for making rmap 4 ;)))                          (me)
rmap 4:
  - look at the referenced bits in page tables                        (me)
rmap 3:
  - forgot one FASTCALL definition                                    (me)
rmap 2:
  - teach try_to_unmap_one() about mremap()                           (me)
  - don't assign swap space to pages with buffers                     (me)
  - make the rmap.c functions FASTCALL / inline                       (me)
rmap 1:
  - fix the swap leak in rmap 0                           (Dave McCracken)
rmap 0:
  - port of reverse mapping VM to 2.4.16                              (me)

regards,

Rik
