One of my collaborators has caught that I have mischaracterized one of the
below-listed proposals - in it's very title. I will include a change to this
in r1. Please see below for correction.

I have tendered several proposals for consideration under ZBC. I'd love to be
able to present these in today's call.
14-181R0 2014/07/07 ZBC Discussion: Active zones and host managed pinning
- a view of the transitions between zone conditions, and a means for hosts to
control where latencies due to resource management are incurred
14-182R0 2014/07/07 ZBC: Read across sequential write required zone boundary
14-183R0 2014/07/07 ZBC: Read unwritten sequential write required zone
- two related optional behavioral changes with indications thereof
14-184R0 2014/07/07 ZBC: Disallow unaligned writes for host aware devices
Should be: "ZBC: Disallow unaligned writes for host aware managed devices"
- why must we support unaligned accesses on conventional zones on host
managed zoned block devices? Just say no.
Thanks -
