From 2f19721faf274aac3b073bf4fd810079dc38e0e1 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 10 Oct 2018 08:08:20 -0700 Subject: [PATCH] nvmet-fcloop: suppress a compiler warning [ Upstream commit 1216e9ef18b84f4fb5934792368fb01eb3540520 ] Building with W=1 enables the compiler warning -Wimplicit-fallthrough=3. That option does not recognize the fall-through comment in the fcloop driver. Add a fall-through comment that is recognized for -Wimplicit-fallthrough=3. This patch avoids that the compiler reports the following warning when building with W=1: drivers/nvme/target/fcloop.c:647:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (op == NVMET_FCOP_READDATA) ^ Signed-off-by: Bart Van Assche Reviewed-by: James Smart Signed-off-by: Christoph Hellwig Signed-off-by: Sasha Levin --- drivers/nvme/target/fcloop.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/nvme/target/fcloop.c b/drivers/nvme/target/fcloop.c index 0b0a4825b3eb..096523d8dd42 100644 --- a/drivers/nvme/target/fcloop.c +++ b/drivers/nvme/target/fcloop.c @@ -535,6 +535,7 @@ fcloop_fcp_op(struct nvmet_fc_target_port *tgtport, break; /* Fall-Thru to RSP handling */ + /* FALLTHRU */ case NVMET_FCOP_RSP: if (fcpreq) { -- 2.20.1
