[ovirt-devel] SPM or SDM for a new verb?

Hi! I'm writing code for a new verb (sparsifyInplace) in VDSM and got two different opinions about whether to use SPM or SDM for it: 1) SDM is the new correct approach, need to use it. 2) SDM is on early stage and may be changed significantly, so it is better to use SPM as mature and reliable approach. What's your opinion? Shmuel
