Yes - but I've run into a different problem.
After fixing up include/rdma to point at drivers/infiniband/include/rdma,
I get a symbol missing from from the modules.


iota:/usr/src/linux-2.6.14# make modules_install

ip_dev_find() is not exported by net/ipv4/fib_frontend.c.

However, drivers/infiniband is the only module that needs this.
CONFIG_IP_MROUTE is another configurable user but cannot be enabled
as a module.

Patch below adds EXPORT_SYMBOL() to fib_frontend.c.
I'm not trying to assert this is the Right Thing.
It's just the first obvious solution to the immediate problem.

thanks,
