[PATCH 2/7] xfs: Use delayed write for inodes rather than async

[Christoph Hellwig]

>  	/*
> -	 * Write out the inode.  The completion routine ('iflush_done') will
> -	 * pull it from the AIL, mark it clean, unlock the flush lock.
> +	 * Push the inode to it's backing buffer. This will not remove
> +	 * the inode from the AIL - a further push will be required to trigger
> +	 * a buffer push. However, this allows all the dirty inodes to be pushed to

Btw, this creates a rather annoying and pointless too long line in the
source file.
