The concept is fine, but:

>> -static void bdev_write_inode(struct inode *inode)
>> +static void bdev_write_inode(struct block_device *bdev)
>>  {
>> +	struct inode *inode = bdev->bd_inode;
>> +	int ret;
>> +
>>  	spin_lock(&inode->i_lock);
>>  	while (inode->i_state & I_DIRTY) {
>>  		spin_unlock(&inode->i_lock);
>> -		WARN_ON_ONCE(write_inode_now(inode, true));
>> +		ret = write_inode_now(inode, true);
>> +		if (ret) {
>> +			char name[BDEVNAME_SIZE] = "";

that initializer isn't necessary.

Cheers,
Jeff
