This is because kprobe.* probes cannot currently be tested
for validity at translate time. If the logic looked through
a symbol table of some sort, it could work. It could then
expand wildcards.
session.exported_symbols is actually a plausible source of
such data, even though it's only a subset. $kernel-builddir/System.map
is another plausible source.
