Hallo Nab,

I just did a little bit of stress testing:

        - Rescan from 12 Initiators at the same time - PASS
        - Deployed 24 VMs over 12 Initiators at the same time 200 MB/s
          frontend traffic - PASS
        - Booted 24 VMs on 12 ESX servers at the same time - 120 MB/s
          frontend traffic - PASS
        - Did 24 svMotion at the same time - 400 MB/s backend traffic -
          10 MB/s frontend traffic using XCOPY. - PASS
        - Unloaded the target in production, ran 'grep se_tmr
          /proc/slabinfo' and loaded it again. And made sure that the
          VMs continued to run. - PASS

It looks pretty stable to me. I'll use it next week in a class and
report back if I had any issues whatsoever. This was with:

v3.12-rc3-4-g8a77fe9

Cheers,
        Thomas
