Kal Conley 1ba83f505c xsk: Elide base_addr comparison in xp_unaligned_validate_desc ... Remove redundant (base_addr >= pool->addrs_cnt) comparison from the conditional. In particular, addr is computed as: addr = base_addr + offset ... where base_addr and offset are stored as 48-bit and 16-bit unsigned integers, respectively. The above sum cannot overflow u64 since base_addr has a maximum value of 0x0000ffffffffffff and offset has a maximum value of 0xffff (implying a maximum sum of 0x000100000000fffe). Since overflow is impossible, it follows that addr >= base_addr. Now if (base_addr >= pool->addrs_cnt), then clearly: addr >= base_addr >= pool->addrs_cnt Thus, (base_addr >= pool->addrs_cnt) implies (addr >= pool->addrs_cnt). Subsequently, the former comparison is unnecessary in the conditional since for any boolean expressions A and B, (A || B) && (A -> B) is equivalent to B.
