Why not relocating this check before f2fs_map_blocks()?
Wait, it supports DIO in multi-device image after commit 71f2c8206202
("f2fs: multidevice: support direct IO"), how about
checking with f2fs_allow_multi_device_dio()?
Thanks,
Thanks,

Are you talking about the check for !f2fs_is_multi_device()? It could go in
either location, but I think it makes the most sense to have it right before the
line that uses 'inode->i_sb->s_bdev', since that is the place which makes the
assumption that the filesystem has only one block device.
