[PATCH] trivial, document that div64_u64() is not precise on 32bit platforms
We have a bugreport which blames div64_u64() on 32bit platforms. However, the code obviously doesn't even try to pretend it can do the 64bit division precisely. If there is something in the high word of divisor, div64_u64() just shifts both arguments and throws out the low bits. Add a small comment to avoid th... 2 Aug 2010 12:33
