I am guessing that you are getting an unresolved symbol. Modifying the
system call table is not and probably never will be available for
modules. The syscall table is very architecture dependant, and is not

you do not need to trace system calls then. Provide a misc char device,
and get the user app to open it. Then you

anyway, you can just put refcounts in your hijacked system calls; that is
the safe way to do it, and doesn't require any kernel patches, just extra
cost in the intercepted system calls.
