In the course of review, some concerns were surfaced about the
original virtio-blk lifetime proposal, as it depends on the eMMC
spec which is not open

Add a more detailed description of the meaning of the fields
added by that proposal to the virtio-blk specification, as to
make it feasible to understand and implement the new lifetime
metrics feature without needing to refer to JEDEC's specification

This patch does not change the meaning of those fields nor add
any new fields, but it is intended to provide an open and more
clear description of the meaning associated with those fields.

Changes in v2:
  - clarified JEDEC references;
  - added VIRTIO_BLK prefix and cleaned up comment syntax;
  - clarified reserved block references

Is there any outstanding feedback from the linux-block folks? I've lost
track of this, I'm afraid. (Your R-b is the only feedback I see on this
list...)

We can certainly put up a vote. This is one of the things I wanted to
see fixed for the next release of the standard.

I have CCed Christoph, linux-block@, and virtualization@. Here is the
link to the patch that we're discussing:
