Hello Greg,
Please provide a cover letter when posting a patch series. Such a cover
letter is not only informative but also makes it easy for people who want
to comment on a patch series as a whole. I have a question that applies
to the entire patch series. The RDMA/CM code defines functions like
rdma_create_id() and rdma_create_qp(). If I search through the kernel tree
for callers of these functions then I find several more kernel modules than
the ones that are modified by this patch series:
$ git grep -lE '[[:blank:]](rdma_create_id|rdma_create_qp)\('
drivers/infiniband/core/cma.c
drivers/infiniband/ulp/iser/iser_verbs.c
drivers/infiniband/ulp/isert/ib_isert.c
drivers/infiniband/ulp/srp/ib_srp.c
drivers/infiniband/ulp/srpt/ib_srpt.c
drivers/nvme/host/rdma.c
drivers/nvme/target/rdma.c
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd.c
drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd.h
fs/cifs/smbdirect.c
include/rdma/rdma_cm.h
net/9p/trans_rdma.c
net/rds/ib.c
net/rds/ib_cm.c
net/rds/rdma_transport.c
net/sunrpc/xprtrdma/svc_rdma_transport.c
net/sunrpc/xprtrdma/verbs.c
Are you sure that this patch series is complete?
Thanks,
Bart.
