Brad Lewis cb70964221 8659 static dtrace probes unavailable on non-GPL modules
ZFS tracing efforts are hampered by the inability to access zfs static
probes(probes using DTRACE_PROBE macros). The probes are available via
tracepoints for GPL modules only.  The build could be modified to
generate a function for each unique DTRACE_PROBE invocation. These could
be then accessed via kprobes.
