Subject: [ndctl PATCH v3] ndctl/lib: fix symbol redefinitions reported by
GCC10
A toolchain update in Fedora 32 caused new compile errors due to
multiple definitions of dimm_ops structures. The declarations in
'private.h' for the various NFIT families are present so that libndctl
can find all the per-family dimm-ops. However they need to be declared
as extern because the actual definitions are in <family>.c.
Additionally, 'param' instances in list.c and monitor.c need to be
marked as static.
