Hi-
I've tested this with two kinds of systems:
1. A system with no physical RDMA devices and no start-up
scripts to load these modules
2. A system with physical RDMA devices and with the start-up
scripts that load xprtrdma/svcrdma
In both cases, after doing an "rmmod rpcrdma", I can mount
a "proto=rdma" mount or start the NFS server, and the module
gets reloaded automatically.
I therefore believe it is safe to delete the code in the
rdma-core start-up scripts that manually load RPC-related
RDMA support. Either the sunrpc.ko module does this, or NFS
user space handles it. There's no need for the rdma-core
scripting.
I didn't know that rdma-core does this... it really shouldn't, the
mount should (and does) handle it.
I also see that srp(t) and iser(t) are loaded too.. IIRC these are
loaded by their userspace counterparts as well (or at least they
should).
