From e690c9e3f4fb2cc589414c5bf502dcfe04e685de Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Thu, 10 Jan 2019 15:52:25 -0600 Subject: afs: Mark expected switch fall-throughs In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in many cases I placed a /* Fall through */ comment at the bottom of the case, which what GCC is expecting to find. In other cases I had to tweak a bit the format of the comments.
