Hi all,

After merging the cifs tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:

fs/cifs/sess.c: In function 'cifs_select_sectype':
fs/cifs/sess.c:527:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
switch (requested) {
fs/cifs/sess.c:540:2: note: here
fs/cifs/connect.c: In function 'cifs_parse_mount_options':
fs/cifs/connect.c:1825:8: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!(tmp_end < end && tmp_end[1] == delim)) {
fs/cifs/connect.c:1832:3: note: here
case Opt_pass:

Exposed by my use of -Wimplicit-fallthrough

I am not sure why these only turned up now (as opposed to earlier today).
