Hi all, After merging the rdma tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
drivers/infiniband/hw/hfi1/tid_rdma.c: In function
'hfi1_tid_rdma_wqe_interlock':
drivers/infiniband/hw/hfi1/tid_rdma.c:3251:3: warning: this statement may fall
through [-Wimplicit-fallthrough=]
switch (prev->wr.opcode) {
^~~~~~
drivers/infiniband/hw/hfi1/tid_rdma.c:3259:2: note: here
case IB_WR_RDMA_READ:
^~~~
Introduced by commit
c6c231175ccd ("IB/hfi1: Add interlock between TID RDMA WRITE and other
requests")
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).
