Hi Bart,
do you have some benchmark numbers using the common ULPs
(SRP/iSER/NVMe-RDMA) ?
I can run NVMe-RDMA (using ConnectX-5) in my lab till EOW and send the
results.

Hello Jason and Doug,
The RDMA functions that submit a work request accept a work request pointer as
input but do not modify that work request. This patch series makes this
explicit by declaring these pointers const. That change allows the compiler to
verify that the input work request is not modified. Please consider these
patches for kernel v4.19.
Thanks,
Bart.
Changes compared to v2:
- Addressed Leon's feedback in patch 3/4, the patch that modifies begin_wqe()
in the mlx5 driver.
- Removed a whitespace-only change from patch 2/4.
Changes compared to v1:
- Instead of only modifying the RDMA hw and sw drivers, also modify ib_post_*()
and all ULP drivers.
Bart Van Assche (4):
IB/iser: Inline two work request conversion functions
RDMA: Constify the argument of the work request conversion functions
IB/mlx5, ib_post_send(), IB_WR_REG_SIG_MR: Do not modify the 'wr'
argument
RDMA, core and ULPs: Declare ib_post_send() and ib_post_recv()
arguments const
