The Debian kernel team received a request to enable this config option
in our packaged kernels for x86-64, with reference to
Documentation/x86/x86_64/fake-numa-for-cpusets. This document seems to
encourage the use this option in production. However, the Kconfig help
text for this says (as it has done from the beginning of git history):
Enable NUMA emulation. A flat machine will be split
into virtual nodes when booted with "numa=fake=N", where N is the
number of nodes. This is only useful for debugging.
Please could you clarify whether you think this is really suitable for
production use, in particular whether it would be sane to enable the
config option in a distribution kernel?
Ben.
