Commit 7321f19d ("crush: straw2 bucket type with an efficient 64-bit crush_ln()").

+                       draw = ln / w;

where 'ln' is 64 bit.

Some other oddies in that patch, such as 

+#if defined(__linux__)
+#include <linux/types.h>
+#elif defined(__FreeBSD__)
+#include <sys/types.h>
+#endif

and lots of coding style violations.
