Re: [PATCH v2] nvme: skip the zoned limits update if the zone info query failed

Hi Damien,

Thanks for taking a look.

Christoph already answered this, and I agree with him: the split return
is deliberate and a common pattern in the nvme driver, because some
callers do need to tell a controller-reported status apart from a local
errno.  This function is one of them: it opens with "ret =
nvme_identify_ns(...); if (ret) return ret;", and nvme_validate_ns()
then only removes the namespace on "ret > 0 && (ret & NVME_STATUS_DNR)",
which it could not do if the status had been folded into an errno.

So I kept the fix at the call site rather than changing the calling
convention.

Thanks,
Chao
