commit 098cdab16dfa6a85e9dad2cad604dee14ee15f66
Author: Dave Anderson <anderson@redhat.com>
Date:   Fri Feb 12 14:32:53 2016 -0500

Fix for the changes made to the kernel module structure introduced by
    this kernel commit for Linux 4.5 and later kernels:
    
      commit 8244062ef1e54502ef55f54cced659913f244c3e
      modules: fix longstanding /proc/kallsyms vs module insertion race.
    
    Without the patch, the crash session fails during initialization
    with the error message: "crash: invalid structure member offset:
    module_num_symtab".
