For this speficic example, I don't understand, 
It's always call activate_volumes , and maybe mount loop devices on some condition.

ok, I can simply keep activate_volumes separate from losetup.
I'll rework my patches.

I do not like this whole series, because you define 
subroutines with unexpected side effects. 

For example, an naive developer want to call: 

mountpoint_activate('rootfs', ...) 

which does nothing for some reason? 

You should really do those checks somewhere else. 

Also, we want to activate/deactivate all volumes at once, because 

PVE::Storage::activate_volumes($storage_cfg, [...]); 

can take several $volids, and is optimized to activate each 
storage only once.
