In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: In file included from drivers/block/drbd/drbd_actlog.c:30: drivers/block/drbd/drbd_int.h: In function ‘__drbd_chk_io_error_’: drivers/block/drbd/drbd_int.h:1774:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (df == DRBD_READ_ERROR || df == DRBD_WRITE_ERROR) { ^ drivers/block/drbd/drbd_int.h:1782:2: note: here case EP_DETACH: ^~~~ drivers/block/drbd/drbd_req.c: In function ‘__req_mod’: drivers/block/drbd/drbd_req.c:856:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (!(req->rq_state & RQ_NET_OK)) { ^ CC [M] fs/btrfs/inode-map.o drivers/block/drbd/drbd_req.c:871:2: note: here case BARRIER_ACKED: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that in some cases, the code comment is modified in accordance with what GCC is expecting to find.
