Hi Jan,

commit: 2420b4fa98f2cac1e765785f2190b16830d8da4b [92/99] vfs: Reorder operations during sys_sync
config: i386-randconfig-b001 (attached as .config)

All related error/warning messages:

fs/sync.c: In function 'writeback_inodes_one_sb':
fs/sync.c:79:3: error: too few arguments to function 'writeback_inodes_sb'

vim +79 fs/sync.c
    76	static void writeback_inodes_one_sb(struct super_block *sb, void *arg)
    77	{
    78		if (!(sb->s_flags & MS_RDONLY))
  > 79			writeback_inodes_sb(sb);
    80	}
    81	
    82	static void sync_fs_one_sb(struct super_block *sb, void *arg)

The expected prototype is:

void writeback_inodes_sb(struct super_block *sb, enum wb_reason reason);
