| |
Hi all,
After merging the rdma tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
drivers/infiniband/hw/hfi1/qp.c: In function 'hfi1_setup_wqe': drivers/infiniband/hw/hfi1/qp.c:328:3: warning: this statement may fall through [-Wimplicit-fallthrough=] hfi1_setup_tid_rdma_wqe(qp, wqe); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/infiniband/hw/hfi1/qp.c:329:2: note: here case IB_QPT_UC: ^~~~
Introduced by commit
f1ab4efa6d32 ("IB/hfi1: Enable TID RDMA READ protocol")
I get this warning because I am building with -Wimplicit-fallthrough in attempt to catch new additions early. The gcc warning can be turned off by adding a /* fall through */ comment at the point the fall through happens (assuming that the fall through is intentional).
