In T10-PI support we will have memory keys for protection
buffers and signature transactions. We prefer to compact
indicators rather than keeping multiple bools.
This commit does not change any functionality.

This block doesn't apply either..
ISER_FRWR_LI_WRID does not appear to be defined anywhere in v3.14-rc2

Er, missed the bit wrt:
IB/iser: Suppress completion for fast registration work requests
Applied along with ib_iser + ib_isert patches to target-pending/rdma-dif
--nab
OK, I see you got the missing piece.
This fixes all your conflicts right (I verified it before myself)?
