I'm definitely nit-picking here, but this should probably be: if (chunk_offset % expected_alignment) without the trailing "!= 0". I don't have a strong preference here, since we are doing a comparison of an arithmetic operation against an (un-)expected value. But I think the CodingGuidelines would technically call this out of style...
I suppose so, but somehow I consider the subtlety of "%" to merit the more explicit comparison (versus something like "if (foo)"). Grepping for "if (.* %)' seems to show some of both. -Peff
