What I was trying to point out was that storage people try to treat
SSDs as HDDs... and SSDs are very different. Harddrives mostly survive
powerfails (with emergency parking), while it is very, very difficult
to make SSD survive random powerfail, and we have to make sure we
always powerdown SSDs "cleanly".

We do.

The issue raised is that some SSDs still increment the unexpected
power loss count even after clean shutdown sequence and that the
kernel should wait for some secs before powering off.

We can do that for select devices but I want something more than "this
SMART counter is getting incremented" before doing that.

Thanks.
