Subject: [PATCH] f2fs: avoid build warn of fall_through
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:
