o ACTIVE is no longer a status flag - lv_active() used to check if an LV
...
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.

PV is allocatable - free extents on it may be allocated to LVs

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.

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.
