File vdsm/storage/sp.py
Line 1879:         # Acquiring the lock on the image only if it's not a snapshot
It's not very clear.
Do you mean 'Acquiring the lock on the image only if created volume not a 
snapshot' ?

Line 1880:         if (imgUUID != srcImgUUID) or (volFormat != 
volume.COW_FORMAT):
why (imgUUID != srcImgUUID)  ?  Actually it's OK to get srcImgUUID as zero-UUID 
for snapshot, it's mean 'Create snapshot on the same iamge'.
If you want to do this you need to check (volUUID != srcVolUUID).

Line 1899:         return dict(uuid=uuid)
Gennerally, I am not really happy with this change. If you decided create 
snapshots without locking, why you need locking at all? Only for base volumes ?
Anyway, why this related to 'clone volume' patch?

....................................................
File vdsm/storage/volume.py
Line 876:     size = int(size)
Do you aware that sometimes we pass 'size' parameter in sectors? Did you 
checked that in all appearances of volume.createVolume() you have right 'size' ?
