#     scripts/decode_stacktrace: warn when modpath is needed but is unset
#     
#     When a user tries to parse a symbol located inside a module he must have
#     modpath set. Otherwise, decode_stacktrace won't be able to parse the
#     symbol correctly.
#     
#     Right now the failure is silent and easily missed by the user. What's
#     worse is that by the time the user realizes what happened (or someone on
#     LKML asks him to add the modpath and re-run), he might have already got
#     rid of the vmlinux/modules.
