We also can't rely on 4-byte alignment though, so perhaps we should do
something like
u32 sta_info_hash(void *addr, u32 len, u32 seed)
{
u16 *a = addr;
return jhash_3words(a[0], a[1], a[2], seed);
}Or better do return jhash_2words(addr[0], (addr[1] << 16) | addr[2], seed); since I have no idea how the missing high 16 bits would behave. (we can rely on 2-byte alignment, but not 4-byte) johannes
