Hi Or,
Here are two more iser-target discovery related patches that I'm
including into for-next code now..
Hi Nic,
Using your tree for-next branch and the initiator patch I posted to the
open-iscsi list last week
I was able to have discovery going through iSER, cool.
At some point I got the below trace I see it says "the code is fine but
needs lockdep annotation"
Or.
Set np->np_transport to ffffffffa037d0e0 -> iSCSI/TCP
Set np->np_transport to ffffffffa03af000 -> IB/iSER
lio_target_np_store_iser() done, op: 1
target_core_get_fabric() failed for fc
target_core_get_fabric() failed for qla2xxx
MAD registration failed for mlx4_0-1.
srpt_add_one(mlx4_0) failed.
