[PATCH] nvme: NVME_TCP_OFFLOAD should not default to m

[PATCH] nvme: NVME_TCP_OFFLOAD should not default to m

[Geert Uytterhoeven]

The help text for the symbol controlling support for the NVM Express
over Fabrics TCP offload common layer suggests to not enable this
support when unsure.

Hence drop the "default m", which actually means "default y" if
CONFIG_MODULES is not enabled.

Err, where did this appear from?  This code has not been accepted into
the NVMe tree and is indeed not acceptable in this form.

It was applied to net-next.

please drop the nvme code from net-next

Hi Dave,

please drop the nvme-offload code from net-next.  Code for drivers/nvme/
needs ACKs from us nvme maintainers and for something this significant
also needs to go through the NVMe tree.  And this code is not ready yet.

Please send me a revert, and I will apply it, thank you.

It's tricky because at least one driver uses the new interfaces.

Thank you.

Shouldn't whoever merged un-ACK'ed patches from a different subsystem
get to own the tricky revert?
