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.

74af29faae o I was reading striped volumes incorrectly. 2001-11-29 14:13:43 +00:00

d5880f97c5 o Confusingly, dmfs-tdir isn't gone, its now called dmfs-lv.c and its the
old dmfs-lv.c thats gone.
 o Dropped out support for multiple tables in line with ioctl interface
 o Some reordering to better support the userland library
 o Updated to 2.4.16

I'm fairly happy with the way that this is working now, so the next job is
to start the integration with the ioctl interface so there is a single
common dm.[ch] and selectable interfaces (fs or ioctl).

Further improvements can be made even now, but I hope to wait until we've
got this going and integrated and the libdm parts working as well before
investigating other avenues.

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.
