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
...
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F System.map  2.

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,

...never mind. Johann George just pointed out someone already has
added this diff to the openib.org repository:
	https://openib.org/svn/gen2/trunk/src/linux-kernel/patches/linux-2.6.14-fib-frontend.diff

sorry,
