__wsum csum_partial_copy_from_user	(	const void __user *	src,
		void *	dst,
		int	len,
		__wsum	isum,
		int *	errp
	)

csum_partial_copy_from_user - Copy and checksum from user space. : source address (user space) : destination address : number of bytes to be copied. : initial sum that is added into the result (32bit unfolded) : set to -EFAULT for an bad source address.

Returns an 32bit unfolded checksum of the buffer. src and dst are best aligned to 64bits.

__wsum csum_partial_copy_nocheck	(	const void *	src,
		void *	dst,
		int	len,
		__wsum	sum
	)

csum_partial_copy_nocheck - Copy and checksum. : source address : destination address : number of bytes to be copied. : initial sum that is added into the result (32bit unfolded)

Returns an 32bit unfolded checksum of the buffer.
