Subject: linux-next: build warning after merge of the f2fs tree

Hi Jaegeuk,

After merging the f2fs tree, today's linux-next build
(x86_64_allmodconfig) produced this warning:

In file included from fs/f2fs/dir.c:11:
fs/f2fs/f2fs.h: In function '__mark_inode_dirty_flag':
fs/f2fs/f2fs.h:2388:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (set)
      ^
fs/f2fs/f2fs.h:2390:2: note: here
  case FI_DATA_EXIST:
  ^~~~

Exposed by my use of -Wimplicit-fallthrough

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