Subject: IB/core: Move rdma_is_upper_dev_rcu to header file
X-Git-Tag: microblaze-4.7-rc1~639^2~141
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=6020d7e5004cc8591d61d449e9285a6f08279541;p=linux-2.6-microblaze.git

IB/core: Move rdma_is_upper_dev_rcu to header file

In order to validate the route, we need an easy way to check if a
net-device belongs to our RDMA device. Move this helper function
to a header file in order to make this check easier.
