csum_partial_copy

Name:Note: when you get a NULL pointer exception here this means someone* passed in an incorrect kernel address to one of these functions.* If you use these functions directly please don't forget the* access_ok().

Proto:static inline __wsum csum_partial_copy_nocheck(const void *src, void *dst, int len, __wsum sum)

Type:__wsum

Parameter:

Type	Parameter	Name
const void *	src
void *	dst
int	len
__wsum	sum

Return he same as csum_partial, but copies from src while it* checksums, and handles user-space pointer exceptions correctly, when needed.* here even more important to align src and dst on a 32-bit (or even* better 64-bit) boundary
