Oops, sorry, I didn't notice there is unnecessary f2fs_truncate_meta_caches()
in f2fs_wait_on_block_writeback_range(), so still we'd better just use
f2fs_wait_on_block_writeback here?

    void f2fs_wait_on_block_writeback_range(struct inode *inode, block_t blkaddr,
                                    block_t len)
    {
        struct f2fs_sb_info *sbi = F2FS_I_SB(inode);
        block_t i;

        if (!f2fs_meta_inode_gc_required(inode))
            return;

        for (i = 0; i < len; i++)
            f2fs_wait_on_block_writeback(inode, blkaddr + i);

        f2fs_truncate_meta_caches(sbi, blkaddr, len);  <------------
    }

Thanks,
