The reason I'm asking is because while this patch fixes your driver
everybody else will still crash and burn should something like this
happen again.
A number of other drivers already have similar sg-count functions in
them.
Perhaps you can help abstract this into a helper that everybody can
call?
I can do that. Something like an sg_nents_for_len() function that takes
an sg pointer and a u64 length as arguments. The function should also
return an error if the length requirement isn't satisfied.
Thanks,
