Subject: Re: [PATCH V2 1/2] xen/granttable: Support sub-page grants
Date: Fri, 09 Dec 2011 13:19:09 +0800	[thread overview]
Message-ID: <4EE19A4D.9030500@oracle.com> (raw)

Hi Paul,

>>> #define get_free_entry()	get_free_entries(1)
Is this necessary? Maybe you defined this to keep consistence with 
put_free_entry(ref)?
But other functions such as gnttab_grant_foreign_transfer and 
gnttab_grant_foreign_access all call get_free_entries(1). Maybe it is 
better to keep initial get_free_entries(1) code?

Thanks
Annie
