| |
Hi all,
After merging the net-next tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
drivers/net/ethernet/netronome/nfp/flower/offload.c: In function 'nfp_flower_copy_pre_actions': drivers/net/ethernet/netronome/nfp/flower/offload.c:630:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (tunnel_act) ^ drivers/net/ethernet/netronome/nfp/flower/offload.c:632:3: note: here case NFP_FL_ACTION_OPCODE_PRE_LAG: ^~~~
Introduced by commit
1c6952ca587d ("nfp: flower: generate merge flow rule")
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).
