Subject: [PATCH] xen/9pfs: mark expected switch fall-through in xen_9pfs_front_changed
Date: Sun, 15 Oct 2017 13:08:40 -0500	[thread overview]
Message-ID: <20171015180840.GA7305@embeddedor.com> (raw)

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. Silva <garsilva@embeddedor.com>

This code was tested by compilation only (GCC 7.2.0 was used).
