Hello Doug,
The five patches in this series modify the RDMA RW API slightly. This is
needed to avoid that the SRP and iSER target drivers submit RDMA
requests with an SGE list that exceeds the queue pair limits. The
ib_srpt changes in this series have been tested but the ib_isert changes
not yet.
The changes compared to v3 of this patch series are:
* Split the single QP SGE limit into separate READ and WRITE SGE limits.
* Added a comment in ib_srpt.h that explains where the SGE limit comes
from.
Changes compared to v2:
* For RDMA READs, limit SGE back to dev->attrs.max_sge_rd for iWARP.
Changes compared to v1:
* max_send_sge is now stored in struct ib_qp. This greatly simplifies
this patch series.
* An unneeded initialization that I had added to rdma_rw_init_one_mr()
has been left out again.
* Corrected "Fixes" tag in the patch description where needed.
The individual patches in this series are:
0001-IB-core-Make-rdma_rw_ctx_init-initialize-all-used-fi.patch
0002-IB-core-RDMA-RW-API-Do-not-exceed-QP-SGE-send-limit.patch
0003-IB-srpt-Limit-the-number-of-SG-elements-per-work-req.patch
0004-IB-srpt-Simplify-srpt_queue_response.patch
0005-IB-isert-Remove-an-unused-member-variable.patch
Thanks,
Bart.
