Hi all,

so here we go, FINAL v4.3. This is the 3rd maintenance update for WOLK4.0.
Due to popular request, four new features.

NOTE: If almost no one is able to file real bugreports, don't expect
      _ANYTHING_ get fixed for your problems!

The files will appear somewhen within the next hour at sf.net file section and
sourceforge mirrors.

Have fun :-)



Changelog from v4.2s -> v4.3s
- -----------------------------
o   add:      allows O_DIRECT writes I/O to run in parallel (not serialized
                anymore by the i_sem).
o   add:      extended OOM killer functions via /proc
                Max childs per parent oom-killed before we kill the parent
                tunable via "/proc/sys/vm/oom_parent_expire"
                Min numbers of seconds before we forget about parents
                tunable via "/proc/sys/vm/oom_parent_max"
o   add:      workaround for annoying "APIC error on CPUx" error messages
o   fixed:    large routing table problems with new hash algo (jenkins)
o   fixed:    unexpected IO-APIC
o   fixed:    ext3fs htree sets the index too early
o   fixed:    dmesg cleanup: printf CPU inconsistency
o   fixed:    dnotify read/writev
o   fixed:    buffer_insert_list should use list_add_tail
o   fixed:    cleanup kmem_cache_reap()
o   fixed:    smp race condition in submit_bh (though nearly impossible to
                trigger) and put some BUG_ON to verify nobody calls writepage
                w/o a reference on the page (SetPageUptodate needs it too)
o   fixed:    grsec: pci bios problem on smp w/ kernexec
o   fixed:    grsec: oops on init if we're out of memory
o   fixed:    RMAP: sequential writeout performance tuning
o   fixed:    RMAP: rate limit slab cache pruning, to reduce IPI load
                      on SMP systems
o   fixed:    RMAP: don't cache-align buffer heads, in order to save space
o   fixed:    RMAP: shrink kiobuf slab when reclaiming buffer heads
o   fixed:    RMAP: if we reset the zone size due to highmem being
                      all IO space, we shouldn't BUG() when we see such
                      zones in the page allocator
o   fixed:    RMAP: corner case where all highmem pages are in an
                      IO window and not released into the free list
                      at bootup time
o   fixed:    RMAP: compile warnings
o   fixed:    RMAP: call oom killer only when allocations fail
o   fixed:    RMAP: only count the real freeing of pages for the
                      OOM killer
o   fixed:    RMAP: make bdflush writeout smoother
o   fixed:    RMAP: logic inversion in inode reclaim
o   fixed:    RMAP: only reclaim bufferheads on highmem machines,
                      and only when the bufferheads take more than
                      10% of the spage used by pageable low memory.
o   fixed:    RMAP: make OOM killer less agressive
o   fixed:    RMAP: avoid expensive atomic pagetable operation
o   fixed:    RMAP: backport next_and_idx optimisation from 2.5
o   updated:  AIC7xxx v6.2.36 / AIC79xx v1.3.10 (v2003-06-03)
o   updated:  Super FreeS/WAN v1.99.7.3 Final
o   updated:  CODA v6.0.1
o   updated:  HTB v3.12
o   changed:  converted /proc to seq operations
