    Current -next-20191204 contains

    fcport->nvme_flag &= ~NVME_FLAG_REGISTERED;
    fcport->nvme_flag &= ~ NVME_FLAG_DELETING;
    ... and there's no explanation in changelog why removing
    NVME_FLAG_REGISTERED is good idea.

    This patch was mostly cleanup and if you notice on line 541 we are already clearing up NVME_FLAG_REGISTERED flag.

    e84067d743010 (Duane Grigsby 2017-06-21 13:48:43 -0700 541) fcport->nvme_flag &= ~NVME_FLAG_REGISTERED;
    so this patch is just removing duplicate clearing. At some point we will need to fix double line of clearing NVME_FLAG_REGISTERED and NVME_FLAG_DELETING
    in one line. I'll send patch to fix that for net-next.

    Thanks,
    Himanshu

    Are you sure this change is correct and suitable for -stable?
