Quick question here if user executes nvme ns-rescan /dev/nvme1
will following code result in triggering uevent(s) for
the namespace(s( for which there is no change in the size ?

If so is that an expected behavior ?

My old code had a check to see if old_capacity != new_capacity as well.
I can redo those bits if needed.

The expected behaviour is not clear, but the functionality is not broken, user
space should be able to deal with a resize event where the previous capacity
== new capacity IMHO.

I think it makes sense to not bother with a notification unless there
is an actual change.
