net/rds/iw_rdma.c: In function ‘rds_iw_flush_mr_pool’:
net/rds/iw_rdma.c:553:24: error: ‘poll’ undeclared (first use in this function)
net/rds/iw_rdma.c:553:24: note: each undeclared identifier is reported only once for each function it appears in

If you didn't even build test it, I know you didn't test it's
functionality either.

This is crazy.

Well if it's not important enough to even build test this change
before you post it, then it obviously doesn't matter if the RDMA
module crashes the kernel when it's unloaded.
