Subject: [linux-lvm] Do thin volumes use allocation policy?

Do thin volumes still use allocation policy like normal volumes?
That seems against the general idea of having a pool. Especially 
when the actual device in use isn't displayed anyhere.

The output of lvs show the allocation policy of thin volumes
as follows:

lvs
  LV    VG   Attr      LSize  Pool  Origin Data%  Move Log Copy%  Convert
  Pool1 vg01 twi-a-tz- 17.71g                0.00                        
  Thin1 vg01 Vwa-a-tz- 10.00g Pool1          0.00

The lvchange command and some of the others use allocation policy
on thin volumes too.
