Re: [Xen-devel] [PATCH 0/6] grantable and address conversion patches

I attached the patch which restrict netfront to 256 requests.
It'd be good to avoid maintaining the count of available tx grants in
netfront. Instead you could add a new gnttab interface function
gnttab_no_grants() to tell you whether your private grant pool is
exhausted.
I also don't like the changes to clamp number of grant entries. If the
maptrack entry size is a limit then let's fix it. It looks like they
will have to be 8 bytes rather than 4 bytes, and we can then also get
rid of the nasty mixing of flags and ref in a single field.
In any case, the gnttab interface changes and netfront changes are
logically separate patches.
