This series now sets chunk_sectors limit to share stripe size.
Hmm... chunk_sectors for a zoned device is the zone size. So is this all safe
if we are dealing with a zoned block device that also supports atomic writes ?
Not that I know of any such devic

This value in io_min is used to configure any atomic write limit for the
stacked device. The idea is that the atomic write unit max is a
power-of-2 factor of the stripe size, and the stripe size is available
in io_min.
Using io_min causes issues, as:
a. it may be mutated
b. the check for io_min be
