[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?

Other than that,
