[PATCH 03/17] block: provide a direct_make_request helper

[Sagi Grimberg]

> +/**
> + * direct_make_request - hand a buffer directly to its device driver for I/O
> + * @bio:  The bio describing the location in memory and on the device.
> + *
> + * This function behaves like generic_make_request(), but does not protect
> + * against recursion.  Must only be used if the called driver is known
> + * to not call generic_make_request (or direct_make_request) again from
> + * its make_request function.  (Calling direct_make_request again from
> + * a workqueue is perfectly fine as that doesn't recurse).

Question: are the double spaces on purpose?
