6b4657e81f o I figure if I can't remember how to use my code, then I should add
a comment.  It's quite cool, wish I remember writing it.

75f7aa5563 made the hard-coded 512 into BLOCK_SIZE just for neatness sake.
log_error() if writing the label fails so someone knows which was in error.

faa556e759 Add internal cache holding a 'hint' list of the PVs belonging to each VG.
A substantial speed-up - particularly in readline mode.
If the hints turn out to be wrong, the relevant parts get thrown away.
vgscan destroys it totally.  In both cases it then rebuilds itself as
required.

f4a7ce7c49 - Change label format to include a string disk_type and a version number.
- The iterator can find labels by string and also appropriate version number (==,
  <= or any) if you want.
- Add labels_match() call that compares the two labels and returns an error if
  they do not match.
- Write labels in sector 1 & last rather than 2 & last as per Joe.

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.

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.

170f08cee0 Use CFLAGS during make rule generation. 2001-11-28 12:28:03 +00:00
Joe Thornber
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.
