[PATCH 0/1] nvme: remove CONFIG_NVME_MULTIPATH

[Bryan Gurney]

Device-mapper multipath will no longer be operating on NVMe devices,
so the nvme.core.multipath module parameter can be removed.  This
series also removes the CONFIG_NVME_MULTIPATH kconfig option.

This was tested on the nvme-6.13 branch (currently showing version
6.12-rc4), with particular attention to tests nvme/033-036, and
nvme/039.  These tests still passed after the removal of the
CONFIG_NVME_MULTIPATH parameter (the tests use an "rc" function,
_require_test_dev_is_not_nvme_multipath, that checks for
"nvme-subsystem" in $TEST_DEV_SYSFS, so they do not check for the
existence of CONFIG_NVME_MULTIPATH).

The blktests test nvme/005 checks for the module parameter value of
"nvme_core multipath", but this test gets skipped after this patch.
