A previous patch replaced all irqsave locks in rxe with bh locks. This ran into problems because rdmacm has a bad habit of calling rdma verbs APIs while disabling irqs. This is not allowed during spin_unlock_bh() causing programs that use rdmacm to fail. This patch reverts the changes to locks that had this problem or got dragged into the same mess. After this patch blktests/check -q srp now runs correctly.
