ext4: annotate implicit fall throughs
There is a plan to build the kernel with -Wimplicit-fallthrough and these places in the code produced warnings (W=1). Fix them up. This commit remove the following warnings: fs/ext4/hash.c:233:15: warning: this statement may fall through [-Wimplicit-fallthrough=] fs/ext4/hash.c:246:15: warning: this statement may fall through [-Wimplicit-fallthrough=] Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Andreas Dilger <adilger@dilger.ca>
