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. This patch suppresses ALL missing-break-in-switch false positives in fs/afs Addresses-Coverity-ID: 115042 ("Missing break in switch") Addresses-Coverity-ID: 115043 ("Missing break in switch") Addresses-Coverity-ID: 115045 ("Missing break in switch") Addresses-Coverity-ID: 1357430 ("Missing break in switch") Addresses-Coverity-ID: 115047 ("Missing break in switch") Addresses-Coverity-ID: 115050 ("Missing break in switch") Addresses-Coverity-ID: 115051 ("Missing break in switch") Addresses-Coverity-ID: 1467806 ("Missing break in switch") Addresses-Coverity-ID: 1467807 ("Missing break in switch") Addresses-Coverity-ID: 1467811 ("Missing break in switch") Addresses-Coverity-ID: 115041 ("Missing break in switch") Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Gustavo A.
