Subject: Re: [PATCH] ext4: optimize ext4 direct I/O locking for reading

I've been looking at your patch and testing it, and it looks like
works fine as-is.

The other thing I like about this patch is it allows us to drop
ext4_inode_{block,resume}_unlocked_dio() and EXT4_STATE_DIOREAD_LOCK.

Thanks!!
