[LSF/MM/BPF TOPIC] remove NVMe MP config option

[John Meneghini]

At LSF/MM/BPF next week I will be talking about the CONFIG_NVME_MULTIPATH option.

There has been long discussion on linux-nvme about simplifying the current linux-nvme config options
used to enable/disable support for native nvme multipathing[1][2][3]. Among other confusion about this topic
the the fact that the current upstream kernel produces the following kernel warning when you connect to an
NVMe-oF multipath device when CONFIG_NVME_MULTIPATH=y and nvme_core.multipath=

[  182.863531] nvme nvme4: Found shared namespace 1, but multipathing not supported.
[  182.871030] nvme nvme4: Support for shared namespaces without CONFIG_NVME_MULTIPATH is deprecated and will be removed in Linux 6.0.
  
At LSF/MM/BPF I'd like to discuss my latest patches which attempt to address this subject[4].

Hope to see you there!
