[PATCH 0/4] nvme: make core.nvme_multipath configurable

[John Meneghini <jmeneghi@redhat.com>]

These patches propose an alternative to outright removing the multipath
module parameter. Rather than deleting this module parameter we control
its appearance with a new Kconfig option named NVME_MULTIPATH_PARAM

Note that the default kernel config settings produce a kernel
with no change in functionality. By default both NVME_MULTIPATH
and NVME_MULTIPATH_PARAM are enabled and there are no user visable
changes.

To remove the core.nvme_multipath parameter simply compile with
NVME_MULTIPATH_PARAM=n.

Hopefully this compromise gives everyone what they want.
