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.

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
