Re: [PATCH 05/10] block, nvme: modify rq_integrity_vec function

[Christoph Hellwig <hch@lst.de>]

The subjet is about as useless as it gets :)

The essence is that it should take the iter into account, so name that.

The comment really needs an update.  With this rq_integrity_vec now
is a "normal" iter based operation, that can actually be used by
drivers with multiple integrity segments if it is properly advanced.

No need for the 0 here.
