The newly added nilfs_msg() infrastructure caused a warning in nilfs_clear_dirty_page() when it is disabled:
fs/nilfs2/page.c: In function 'nilfs_clear_dirty_page': fs/nilfs2/page.c:402:22: error: unused variable 'sb' [-Werror=unused-variable] struct super_block *sb = inode->i_sb; We can avoid the warning by adding a cast to void for the first argument of the macro.
