c0ca88c287 o Comparison function was sorting things in ascending rather than
descending order.

o free off the sort array when finished with it.

488a58a998 o Striped allocator
o  Changed pv_map.c to maintain the list of free areas in size order, which
   is more helpful to the allocators.  If you want to allocate a bit of an
   area call consume_area(area, size), this will adjust the area if there's
   some space left and shuffle it to the correct place in the list.


Not tested.

4a8d120415 o pool-debug.c contains an alternative implementation of pool that gets
a seperate chunk of memory from dbg_malloc for each pool_alloc.  This
   will allow the bounds checking code in dbg_malloc to do it's stuff.

o  The normal implementation moved to pool-fast.c

o  pool.c now just contains a #ifdef and includes the appropriate .c file.

Alasdair, could you make sure that gcc -MM get's passed all the
CFLAGS please, otherwise the dependencies get calculated incorrectly.

0bab65915d o Sync up todays work on converting to the segmented representation of
logical volumes.  It includes:

   format1 changes.

   metadata.h changes.

   lv_manip.c changed (striped allocation still not done though).

   activate.c changes.

Nothing has been near a compiler as yet.

Alasdair can you look at changing display.c to use to output the mappings
in a more segment oriented format please ?

I haven't put the span list into struct physical_volume to represent allocated
extents.  I think the burden of maintaining it for things like lv_extend may
out weigh it's uses.

29aa6d5850 o Added dev_open and dev_close functions
o  Changed disk-rep to use these

o  if NDEBUG is not defined the dev_cache will check for open devices on
   teardown.

I was hoping this would speed things up.  But I'm still getting:

reti:/home/joe/sistina/LVM2/tools# time ./lvm vgchange -a n
  Volume group vg0 successfully changed

real    0m5.751s
user    0m0.060s
sys     0m0.070s

even though I have only 1 device with the vg on it passing the filters.
