In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/xen/xen-scsiback.c: In function ‘scsiback_frontend_changed’: drivers/xen/xen-scsiback.c:1185:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (xenbus_dev_is_online(dev)) ^ drivers/xen/xen-scsiback.c:1188:2: note: here case XenbusStateUnknown: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
