Alasdair Kergon	f4cea344b1	improve a few comments in last check-in	2010-03-25 02:40:09 +00:00
Alasdair Kergon	8d6722c8ad	Introduce pv_area_used into allocation algorithm and add debug messages. ... This is the next preparatory step towards better --alloc anywhere support and is not intended to break anything that currently works so please report any problems - segfaults, bogus data in the new debug messages, or if the code now chooses bizarre allocation layouts.	2010-03-25 02:31:48 +00:00
Alasdair Kergon	2c44337bd5	Right, a simple build (without options) is working again.	2008-11-03 22:14:30 +00:00
Alasdair Kergon	be6845999b	Fix inconsistent licence notices: executables are GPLv2; libraries LGPLv2.1.	2007-08-20 20:55:30 +00:00
Alasdair Kergon	2bdc8e1252	Perform high-level free space check before each allocation attempt.	2006-10-23 15:54:51 +00:00
Alasdair Kergon	2262b32057	Use hash, bitset, malloc, pool from libdevmapper.	2005-10-16 23:03:59 +00:00
Alasdair Kergon	7f2def9e6d	Remove lists of free PV segments. ... Simplify pv_maps code and remove slow bitset algorithm.	2005-05-11 15:02:49 +00:00
Alasdair Kergon	6606c3ae81	Update copyright notices.	2004-03-30 19:35:44 +00:00
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
Joe Thornber	15e35a737c	o lv_reduce ... o pv_maps wasn't taking a list of acceptable pvs	2001-11-06 11:19:33 +00:00
Joe Thornber	242019fdf4	o code for building free area lists on a pv. Compiles but not run.	2001-11-05 16:41:38 +00:00
