[Valgrind-users] Handling ioctl 0x30000001 in valgrind?

[Carl P. <cp...@nv...>]

I ran into this output from valgrind

    ==21898== Warning: noted but unhandled ioctl 0x30000001 with no
    size/direction hints.
    ==21898==   This could cause spurious value errors to appear.
    ==21898==   See README_MISSING_SYSCALL_OR_IOCTL for guidance on
    writing a proper wrapper.
    ==21898==   at 0x59C98C7: ioctl (in /lib64/libc-2.12.so)

I'd like to "gracefully" handle this ioctl in valgrind, and looked at 
the instructions posted here

    http://valgrind.org/docs/manual/dist.readme-missing.html

Grep'ing through the files in these directories

    /usr/src/
    /usr/include
    /shared/apps/cuda/CUDA-v7.0.18
    /shared/apps/rhel-6.2/tools/$USER/ValGrind-3.10.1

I can't find anything that maps the address 30000001.
Are these mappings only present for syscalls but not ioctl's?
Or do we need to install a development version of the /usr/src files?
Thanks,

                     Carl
