Alasdair Kergon	b8c919b402	o Metadata area struct change. ... o Support physical extent restrictions on PV lists for allocations e.g. lvcreate -l 200 vg1 /dev/sda1:100-199:300-399	2003-04-24 22:23:24 +00:00
Joe Thornber	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.	2001-11-29 18:45:35 +00:00
