The patch works, but does fail at LD time with:

drivers/built-in.o(.text+0xfd784): In function `iscsi_iser_conn_failure':
drivers/infiniband/ulp/iser/iscsi_iser.c:220: undefined reference to `.iscsi_conn_error'
drivers/built-in.o(.text+0x1003b0): In function `iscsi_iser_exit':
drivers/infiniband/ulp/iser/iscsi_iser.c:1989: undefined reference to `.iscsi_unregister_transport'
drivers/built-in.o(.text+0x10046c): In function `iscsi_iser_init':
drivers/infiniband/ulp/iser/iscsi_iser.c:1978: undefined reference to `.iscsi_register_transport'
drivers/built-in.o(.text+0x100a18): In function `iscsi_iser_control_notify':
drivers/infiniband/ulp/iser/iscsi_iser.c:1855: undefined reference to `.iscsi_recv_pdu'
drivers/built-in.o(.text+0x100bc0):drivers/infiniband/ulp/iser/iscsi_iser.c:1899: undefined reference to `.iscsi_recv_pdu'
drivers/built-in.o(.text+0x100cd4):drivers/infiniband/ulp/iser/iscsi_iser.c:1921: undefined reference to `.iscsi_recv_pdu'

Unfortunately, this causes make to fail, killing the job (I realize
these are technically non-critical errors).

So, I'm just going to disable ISER for now in my tests.

Thanks,
