From 3d8765d4f52a0050343bfa99a1a2aa5ef7d841e5 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Thu, 2 Nov 2017 13:51:22 -0500 Subject: [PATCH] xen/pvcalls-front: mark expected switch fall-through In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case I placed the "fall through" comment on its own line, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R.
