Documentation/infiniband/core_locking.txt states that "The corresponding functions exported to upper level protocol consumers: ... ib_create_ah ... are therefore safe to call from any context."
Which is in turn assumed by bunch of components in the kernel IB stack (look for ib_create_ah calls under drivers/infiniband/core/). The examples you brought here, don't cover them. This way or another, I don't see any reason to break that convension just for the sake of this aspect of the iboe implementation, simply, code with this assumption at hand.
Or.
